Homework Statement
The figure shows a metal coil labored as A. Heading torwards a region where a uniform static magnet field exists, poiting torwards the ground (hence X). The coil moves with the same constant velocity. As it enter the magnet field the coil will have an induced current in it. After a while A leaves the magnet field. Draw a I-T graph showing this scenario.

e=-d(phi)/dt might help but not sure if any equations will help
The Attempt at a Solution
My thoughts. When the coil enter the magnetic field, there will be an induced current that is counterclockwise. When it leaves the magnetic field there will be an induced current that is clockwise. Inbetween there is no current, or is it just constant inbetween? My guess would be that the current is 0 when it dosent leave or enter the magnetic field but I don't know.
So to my questions:
1. How should i know whether the graph should be constant or linear?
2. Is the current counterclockwise a.k.a negative when it enters and clockwise a.k.a positive when it leaves?
3. Is the current 0 inbetween or not?
