Question

Predict what would happen to the strength of the electromagnet in each situation. using a battery with a higher voltage: wrapping the wire around the nail only three times: changing the direction of the current by reversing the battery connections: using a plastic stick in place of the iron nail: holding the nail vertically rather than horizontally:

Answer 1

The the strength of an electromagnet varies with the quantity and direction of current as well as the number of turns in the coil.

What as is an electromagnet?

An electromagnet is a material which operates by the principle of electromagnetism.

Electromagnets possesses both electrical and magnetic properties.

The strength of an electromagnet is affected by the current, the number of turns as well as the material of the electromagnet.

The strength of the given electromagnet will be affected thus:

• increases when using a battery with a higher voltage
• decreases when wrapping the wire around the nail only three times
• is unchanged when changing the direction of the current by reversing the battery connections
• decreases when using a plastic stick in place of the iron nail
• is greatest when holding the nail vertically rather than horizontally.

Therefore, the strength of an electromagnet is affected by current and number of turns in the coil.
