Question

There are four coils of wire being used as electromagnets. They all have the same size and are made up of the same material but have a different number of loops. Which coil will produce a magnetic field with the maximum strength when the same amount of current passes through all coils?a coil having 10 loopsa coil having 25 loopsa coil having 30 loopsa coil having 45 loops

Answer 1

A coil having 45 loops

Step-by-step explanation:

The strength of an electromagnet is proportional to the number of loops. So, when we have more loops, we will get mor strength. It means that the coil that will produce a magnetic field with the maximum strenght is a coil having 45 loops because 45 is the greatest number in the list.
