Right...I really forgot this situation. However if he emphasize the "electric field" not the "charge," I think the answer is still the same?TSny said:E field might induce surface charge on the needle.
An electric field can affect a compass by causing the needle to deflect from its normal north-south orientation. This is because the needle of a compass is a small magnet and is influenced by the magnetic field created by the electric field.
Yes, an electric field can completely reverse the direction of a compass. This is because the electric field can overpower the Earth's magnetic field, which is much weaker, and cause the needle to point in the opposite direction.
Any material that has an electrical charge can create an electric field that can affect a compass. This includes any type of metal, as well as non-metallic materials like plastic and glass.
Yes, the strength of the electric field can affect the amount of deflection in a compass. The stronger the electric field, the greater the deflection in the compass needle will be.
To protect your compass from the effects of an electric field, you can keep it away from any sources of electricity or strong electrical currents. Additionally, storing your compass in a shielded container or using a compass with a non-magnetic needle can also help minimize the impact of an electric field.
