Permanent Magnets. - Always magnetic, always have poles. Induced Magnets. - Materials that are “magnetic” but do not have fixed poles.

In our modern everyday life, the phenomenon of magnetism is associated with iron that is attracted by permanent magnets that can also be made of iron ...

Electromagnetism is a form of magnetism created when current flows through a conductor. When current is present, it generates a magnetic field around the ...

Magnets ​repel and attract other magnets ​and ​attract magnetic materials.​Like poles of magnets repel and opposite poles attract. ○ Non-magnetic materials are ...

In this lesson we shall study about properties of magnets, magnetic effect of current, electromagnetic induction and applications of electromagnets. 5.1 ...

Induced Magnets. Material that becomes magnetic when placed in a magnetic field. Induced magnets can only attract. When the magnetic field is removed an induced.
