Home | Premium Plan | Students | Parents | Teachers | Past Papers | A Level Physics | Shop. We can use magnetic field lines to represent a magnetic field. The earth is also a magnet, it has a north and south pole. Magnetic force is a non-contact force, which means magnets affect each other without touching. The Law of Magnetism states that: Two like poles (S and S or N and N) repel each other. The magnetic field around a current-carrying wire is circular and we use the right-hand thumb rule to determine its direction. Practical Skills.

This is very similar to the motor effect and again, we use Fleming's left hand rule. [CDATA[ There are two types of generator: an alternator (AC) and a dynamo (DC)The force of a magnetic field is given by: force = magnetic field strength x current x length of wire, F = BIl.Transformers are used to step up or step down the potential difference of the National Grid. About me. Magnetism in the New GCSE. The advantage of using an electromagnet is that it can be turned on and off.

Poles When two magnets are close together they exert a force on each other. Now an experienced GCSE and A Level Physics and Maths tutor, Ashika helps to grow and improve our Physics resources. Exam Papers. ngx-pagination install Coconut Water Only two magnets can repel Remember: Field lines never cross The closer the field lines the stronger the field Field lines . We can separate magnets into two categories: 1. Understand that magnets repel and attract other magnets and attract magnetic substances Ferrous & non-ferrous metals describe metals & alloys that do & do not, respectively, contain iron in appreciable amounts. Quick Questions You may also be interested in. Electromagnetism. Magnets are objects which experience attraction and repulsion Like poles repel (push each other apart) For example a north pole will repel a north pole and a south pole will repel a south pole Unlike poles attract (move towards each other) For example a north pole will be attracted to a south pole In this video you'll learn:- The difference between a 'magnet' and a 'magnetic material'- The difference between a permanent and an induced magnet- The 4 mag. 46. A material which has its electrons very aligned will have properties of magnetism. Exam Papers. Imagine a revision book that matches your child's schooling, progresses them at the right level, and therefore improves their topic knowledge . Materials that can be permanently magnetised are magnetically hard.
