"Magnetism, as you recall from physics class, is a powerful force that causes certain items to be attracted to refrigerators." -Dave Barry

Physics is a fundamental subject that can be studied by teenagers across the island of Ireland during their last two years of secondary school.

Many consider the Leaving Certificate subject of physics to be the most interesting of the scientific disciplines due to the fact that teachers encourage students to ask questions and then try to answer them by observing and experimenting.

Leaving Certificate Physics aims to leave students with an understanding of the fundamental principles of physics and its application in everyday life. The subject offers a general education in physics, enabling students to develop an understanding of the scientific method and their ability to observe, think logically and communicate effectively.

Physics is the study of electricity, forces, waves and atomic. During their studies of the physics topics, students also learn more about the most powerful forces in the universe such as magnetism and electromagnetism.

The exam boards that operates in Ireland, have magnetism and electromagnetism as the seventh topic on the Leaving Cert Physics Syllabus and it is divided into the sections of magnetic fields, electromagnets, electromagnetic induction and transformers. 

Superprof is here to create a guide for potential students of the Leaving Cert Physics Syllabus and provide them with all the information that will be covered in this subject in order to help them make an educated decision and decide if this Leaving Cert subject is for them.

By examining the sections included in this topic of the syllabus such as the properties of both Magnetism and Electromagnetism. Students will acquire knowledge that will help them in their future scientific careers. You would be amazed at how many doors will open for you when you develop key problem solving and analytical competencies which surface from an understanding of physics.

Magnetic Fields

If you have clicked on this article then you are either considering taking up physics as a Leaving Certificate subject for your exams, or you are already studying the subject and seeking more information on its associated material.

Let’s dive right into some of the material that you will cover throughout your leaving cert physics course under the chapter of Magnetism and Electromagnetism.

Not all of us come from a scientific background, nor do we have to! If you have never studied physics before at any capacity or simply missed a few days of science as part of the junior cert programme then it is important that we fill you in on some of the terminology associated with the chapter.

When we talk about magnetism we are generally concerned with the magnetic fields that surround magnets. Magnets have two opposite poles, the north-seeking pole of a magnet is known as the north pole and the south-seeking pole is commonly referred to as the south pole.

You might also be familiar with this concept from the earth’s north and south poles. This is just one example that demonstrates how an understanding of physics can help you develop an understanding of the world around us and how it works.

The magnetic field is always stronger near the magnet's poles either north or south.

What else will you need to cover in the chapter?

When preparing for your leaving cert physics exam, Magnetism and Electromagnetism are no different to other topics in how it is assessed each year. Like other similar concepts of physics, magnetism has rules that need to be memorized by students, such as the following:

  • Like poles repel each other, North and North or South and South. For example, if the north pole of the magnet is approached by another north pole it will repel,
  • Unlike poles such as North and South or South and North are attracted to each other. Therefore, it is true when experts of love say that opposites attract!

Depending on the order that you or your teacher decide to navigate the Leaving Cert Physics Syllabus, you may already have studied the topic of forces and understand that magnets are non-contact forces which means that magnets affect each other without touching.

Students learn the basics of a magnetic field in this section of the Physics Syllabus. A magnetic field is known as the region around a magnet where a force acts on another magnet.

While magnetic fields are invisible to the human eye, they can be detected using a small tool known as a magnetic compass. 

The needle of the compass has the four cardinal directions (North, East, South and West) and points in the direction of the Earth's or a magnet's magnetic field.

Drawing a magnetic field is a task expected by students undergoing the Leavin Cert Physics Syllabus. Primary characteristics of drawing a magnetic field include the fact that magnetic field lines never touch, closer the lines = stronger the magnetic field and the lines drawn have arrowheads so that onlookers understand in which direction the force is going.

How to learn about Magnetism and Electromagnetism

Learning a science such as physics and grasping complex topics such as Magnetism and Electromagnetism is a gruelling task for even the most academic students. If you want to progress your competencies by answering exam questions and problem-solving then availing of some physics lessons may be a suitable avenue and next step for you.

Whether you want to progress in order to keep up with the pace of your secondary school physics class or simply want to brush up on your experiments, learning under a teaching professional will help you to pick up some best practice exam techniques.

Availing of a professional teaching professional can have many benefits regardless of what your respective goals and motivation are in the subject. Learning the entire course inside and out can take many years, and while there are no shortcuts to achieving excellence in the subject you could certainly avoid wasting time with needless trial and error!

Physics tutors often will have worked with countless past leaving cert students and mentored them through both the leaving cert examinations. Picking up on some best-practice techniques to employ within your learning can save an ample amount of time, particularly within the early stages. If you are a leaving cert student this is often a popular method of maximising your potential in the subject outside of the classroom.

This can also prove helpful for students who aren’t as confident in their ability to attain a high grade in the subject. If you are looking to kickstart your journey in learning physics, you could learn alone or in groups, you would be surprised what being in a familiar or comfortable environment can do for your learning. After all, consistency is key when learning a subject like physics and it's equally important not to be afraid of making mistakes!
