near the north and south poles of the magnet
Explanation:
Magnetic fields around a permanent magnet is strongest near the north and south poles of the magnet.
Magnetic fields are the region of space around a magnet where magnetic effects are felt.
- This is as a result of a force field that surrounds the magnet.
- Magnetic fields are strongest within the magnet.
- Also, externally, they are strongest at the poles of a magnet.
- Around the poles, magnetic lines of force leaves and enters a magnet.

Answer:
A) is repelled by the sphere
Explanation:
- When a piece of plastic is rubbed with a wooden cloth, it sinks negatively
- Let it change Q. So it is now allowed to touch the neutral zone. Therefore, there is a difference in the surface capacity of the two bodies, so that charge transfer takes place
- Some of its negative charge is transferred to the metal sphere, now both the rod and the sphere are negatively charged and the same chargers as we know are repelled by each other.
- so correct answer is A) is repelled by sphere
Since the current is inversely propotional to its resistance, when the voltage is doubled the current will be one-half
