Fingers = magnetic flux
lines North to South
Thumb = direction
of + charge
Motion (current)
Palm = force
Exerted on
The charge
Centripetal force
On charge caused
By magnetic field
Charge moves in a circular path 2
4. N (magnet) S
By convention (everybody agrees) lines of magnetic
Flux leave the North pole and enter the South pole
Lines of flux are continuous and do not intersect each other.

6. LENZ’S LAW
When a magnet induces a current flow in a conductor, the induced
current flows in a direction so as to create a magnetic field in the
conductor that opposes the original magnet field
