Question

Assuming the same current is running through two separate coils, why is it easier to thrust a magnet into a wire coil with one loop than one with four loops?.

Answer 1

Answer:

Plato/Edmentum Answer

Explanation:

D. because the magnetic field is weaker

Answer 2

The magnetic field strength in a coil is directly proportional to the number of turns, or loops, in the coil.
Therefore, when there are four loops instead of one, the magnetic field strength has increased four times, making it harder to push the magnet in.
