Electromagnetic Forces Quizizz

The more coil wrapped around an electromagnet, the more it...

• Strenthens

• Weakens

• Nothing Changes

In an electromagnet, if you wrap 30 coils around a nail it will collect around 20 paperclips. What do you think will happen if you wrap 50 coils around a nail?

• The nail will still pick up 20 paperclips.

• The nail will pick up less than 20 paperclips.

• The nail will pick up more than 20 paperclips.

• The nail will not pick up any paperclips.
