Permanent Magnets - GCSE Physics

This video introduces permanent magnets and their fields. Around a permanent magnet, like the traditional bar magnet, is a region where other magnets and magnetic materials experience a force. This region is called a magnetic field. The Earth has its own magnetic field, which is why compasses all point in the same direction, towards the North Pole.

The magnetic field of a magnet goes from the north end to the south end. The strength of the magnetic field is represented by how close the field lines are. The closer the field lines are together, the stronger the magnetic field is. The magnetic field between the opposite ends of two magnets is uniform so is represented by parallel lines going from north to south.

Thanks I can now answer my test correctly where in 3rd grading test right now thanks

[cathleen]

Needed this for physics 2! Awesome video very convenient please make more!

[csababarnes]

thanks alot this helped with my upcoming physics test

[aimbotexe]

very helpful and interesting good work

[mumtazhussain]

First time I understand that easily through that picture 🌹🌹🤗🤗 thanks a lot sir 😊😊

[stefansauvageonwhat-a-twis]

Sooo cool, already know knowledge all condensed and well explained

Parmanent magnets are made of?
Steel, soft iron, aluminum or carbon

I have a question, I am aware permanent magnets has no frequency like zero Hz, but why when I use my EMF 390 meter around a permanent magnet it produces 15-21Hz, why did thr magnet produced frequency? is the magnetic field around the magnet moving? or static, Im just curious why I got the frequency, when it should be zero, and I am sure there are no strong interference when I tested those magnets, thank you for your response.

why can't we use the forces of the magnet to create free energy?
