Magnetism
... • The parts of a magnet where the magnetic force is strongest • All magnets have two poles- a north and a south pole • When two magnets come together, a north and south pole attract each other • “Like” poles (north-north or southsouth) repel each other ...

... Ferromagnetic Materials • 1 There are coupled spins in an inner shell of atoms such as iron. In Iron the exchange energy parallels four electron spins. This is a strong enough magnetic moment to align blocks of atoms. • 2. The magnetic susceptibility is positive. • 3. Ferromagnetic material have ma ...

Magnetic Flux
... 2. A circular coil has 10 turns and diameter 2.0 cm. It is placed in a uniform magnetic field of strength 300 mT. The plane of the coil and the direction of the field make an angle of 30 0. Determine the magnetic flux linkage through the coil. Ans : 4.17 X 10-4 Wb 3. A circular coil is placed in a u ...
