1
Q

A
This is a region around a magnet or moving charge where another magnetic body will feel a force
2
Q
What do magnetic field lines show?
A
They show the shape and direction of the field
3
Q
What is a solenoid?
A
This is a long coil of current carrying wire. They show a magnetic field very similar to a bar magnet
4
Q
What is magnetic flux?
A
This is the product of magnetic flux density and and the area perpendicular to the flux. It is measured in webers
5
Q
What is magnetic flux density?
A
Measure of the strength of magnetic field
6
