Question

What could Eric have changed in his electromagnet that caused the decrease in magnetic force from point A to point B? (You MUST give at least 3 possible reasons/changes in the electromagnet)

Answer 1

turns of coil?
current?
hard to say, since you give such scant information

google electromagnets and read about their properties.

Answer 2

help me plz.

Answer 3

im taking it now. if you still need it and if it shows me the answer ill show it here.

Answer 4

HELLLPPPPP MEEEEEEEEEE

Answer 5

One possible change is the number of coils or lose that are wrapped around the metal core that is being used. Another way to decrease the magnetic force is by changing the current flowing through the electromagnet. He could have also change the type of core metal he was using to make the decrease the magnetic force. He could have also change the size of the wire he was using, a smaller wire will increase the resistance and reduce the current flowing weakening the field.
