Question

A coil of conducting wire is connected to a device that measures current. A student has a bar magnet and wants to induce a current in the coil. Which action is most likely to induce the stronger current?O move the bar magnet rapidly up and down near the coilO hold one pole of the bar magnet as close as possible to the coil without touching itO press the side of the bar magnet against as much of the coil as possible O place the bar magnet in the center of the coil

Answer 1

We are given that a person wants to indice a current in a coil using a magnet. We need to use Faraday's law which says that a change in a magnetic field will induce a current in a wire. Therefore, the stundet needs to move the bar magnet rapidly up and down the coil to induce the current. Therefore, the right option is the first option.
