One last qn.
a rectangle coil is placed in a large magnetic field that covers
the coil.
The field's direction is into the paper.
My question is, when you use right hand rule to check direction of
induced current, the current direction of either sides are the
same-up, thus they opposes. So whats the direction of the
current.
[ l----l ]
[ l l ]
[ l l ]
[ l----l ]
Key: the area covered by [ ] is the field.
btw the coil is moving to the right.
the direction of the current does not go in a circle. Instead,
in this case, a potential difference will be formed across the
coil. Just imagine where all the electrons will be moving.
