Which of the following would decrease the strength of an electromagnet? check all that apply

a.) straightening the wire

b.) increasing the current flow

c.) decreasing the voltage

d.) decreasing the resistance

e.) increasing the number of loops of wire

Answer:

The correct answer is:

A. straightening the wire, because the number of turns of the wire around the iron core is directly proportional with  the strength of electromagnet.

and,

C. decreasing the voltage is correct, by decreasing the voltage, the current will decrease and this leads to weaker electromagnet.

Explanation:

Simply, the electromagnet is used to convert electric energy to magnetic energy.

Basic idea:

Components of simple electromagnet:

The strength of electromagnet is simply defined by the strength of magnetic field that synthesized by the electric current.
