Question

Imagine you have two coils close together so that their axes are aligned. You connect the second coil to the power amplifier and you measure the magnetic field in the first coil. If you increase the current through the second coil, the magnetic field in the first coil becomes weaker. becomes stronger. does not change. There is no magnetic field in the first coil.

Step 1

Since the first coil is close to the second coil and their axes are aligned, the magnetic field from the second coil will also affect the first coil. As a result, the magnetic field in the first coil will become stronger due to the increased current in the second Show more…
