electromagnetism Flashcards
1
Q
Domain theory
A
Magnets consist of particles in one direction and are groups of dipoles
2
Q
characteristics of Magnetic fields
A
spacing of lines represent strength
Lines are concentrated at the poles
Go from N pole to S pole outside and inside vice versa
3
Q
More loops =?
A
stronger MF
4
Q
Why are coils called electromagnets
A
because they use electricity to produce a Magnetic field
5
Q
Dipoles
A
Dipoles are lined up in each domain. The domains point in the same direction if magnetized and if not in different directions. They are atomic Magnets
6
Q
Law of poles
A
Like repel
opposite attract
