lisa made the electromagnet shown. what can lisa do to increase the strength of the electromagnet? she can use a nail with weaker magnetic properties. she can change the direction of the nail. she can increase the number of wire loops. she can reduce the current in the wire.

lisa made the electromagnet shown. what can lisa do to increase the strength of the electromagnet? she can use a nail with weaker magnetic properties. she can change the direction of the nail. she can increase the number of wire loops. she can reduce the current in the wire.

Answer

Answer:

She can increase the number of wire loops.

Explanation:

Step1: Recall electromagnet strength factors

Strength depends on current and loops.

Step2: Analyze each option

Using weaker - magnet nail weakens it. Changing nail direction has no effect. Reducing current weakens it. Increasing loops increases magnetic field strength.
