Mr. Smith challenged his students to create an electromagnet that will pick up more paper clips than anyone else in the class. T
immy is very excited and begins to collect all of the necessary materials. He finds a D-cell battery, an iron nail, and a large roll of copper wire. What could Timmy do, using just these materials, to increase the strength of his electromagnet to pick up the maximum amount of paper clips?
Timmy can make the electromagnet strong by the following ways
Using a battery having more voltage and current
By increasing the number of loops
<h2>Explanation:</h2>
An electromagnet can be made by having a source of voltage that is a battery or a cell, a conductor, and metal piece. Wrap insulated copper wire tightly around an iron screw or nail before connecting the wire to a battery. Making sure to leave enough of the wire unwound so that it can be attached to the battery. The more wire is wrapped around the nail, the stronger the electromagnet will be. We can make the flux or strength stronger by increasing the voltage and number of loops of wire.
