Question

2. How might the following things affect the strength of the electromagnet (nail and coil and battery)?

◦ Thickness of the core.
◦ The amount of current going through the wire.
◦ How many times the wire is wrapped around the core

I'm not sure. Thickness of core... smaller magnetic field? Amount of current... same thing? How many times... probably still the same thing? Google isn't turning up good results for me today. Thanks!

Answer 1

Core made of iron, or other ferronickel material. Current x turns is the main factor.

Answer 2

Factors Affecting the Strength of the Magnetic Field of an Electromagnet: Factors that affect the strength of electromagnets are the nature of the core material, strength of the current passing through the core, the number of turns of wire on the core and the shape and size of the core.
