What will happen to this current if a magnet is brought near the cord? A. It will exert a force on the voltage. B. The electric current will stop flowing. C. The resistance of the wire will decrease. D. It will exert a force on the electric current.

The correct answer is D)

Explanation:

When an electric magnet is brought near a cord with an electric current, the cord will most likely deflect away from the magnet because electric fields flowing through a wire generates its own magnetic field.

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

measure their densities same density, same sub
