What happens when a current flows through a wire?
A magnetic field is produced around the wire
2 of 8
How can the shape of the magnetic field be seen as?
A series of concentric circles in a plane, perpendicular to the wire
3 of 8
What does the direction of these field lines depend on?
The direction of the current
4 of 8
What does a wire placed in a magnetic field experience?
A force
5 of 8
What is this force called?
The motor effect
6 of 8
How can the size of the force be increased?
Increasing the strength of the magnetic field, Increase the size of the current
7 of 8
How can the direction of the force be reversed?
If either the direction of the current or the direction of the magnetic field is reversed
