Question

electronics information
which of the following components is found in a simple electromagnet?
a coil of wire
b transistor array
c fiber optic bundle
d bank of capacitors
click the button or type the letter next to your answer.

Explanation:

A simple electromagnet consists of a coil of wire wrapped around a core (usually a ferromagnetic material). When an electric current passes through the coil of wire, it generates a magnetic field. A transistor array is used for switching or amplifying electrical signals. A fiber - optic bundle is for transmitting light signals. A bank of capacitors is for storing electrical energy. So, the component found in a simple electromagnet is a coil of wire.

Answer:

A. coil of wire
