Question

Which electromagnet is the strongest?

An illustration of a metal bar with a coil of wire around it.

An illustration of a metal bar with a coil of wire around it it has more coils.
An illustration of a metal bar with a coil of wire around it it has less coils.

Answer 1

The strength of an electromagnet is directly proportional to the number of turns in the coil of wire, the amount of current flowing through the wire, and the magnetic permeability of the core material. Therefore, an electromagnet with more coils will generally be stronger than one with fewer coils, all other factors being equal.

So, among the given options, the electromagnet with more coils around the metal bar is likely to be the strongest, assuming the same amount of current and core material is used in each electromagnet.

Answer 2

#2

Step-by-step explanation:

The more and closer the coils are the more energy it has because if there are more turns there is more current
