$A$ thin diamagnetic rod is placed vertically between the poles of an electromagnet. When the current in the electromagnet is switched on,the diamagnetic rod is pushed up,out of the horizontal magnetic field. Hence,the rod gains gravitational potential energy. The work required to do this comes from:
- AThe current source
- BThe magnetic field
- CThe induced electric field due to the changing magnetic field
- DThe lattice structure of the material of the rod
