Expert Response


Our Electromagnet is produced by magnetism created by a 9Volt battery,
a tennis ball, and a few wires to carry the charge. It is going to be
suspended by a hanger to move it up and down for 3 inches. We will push
the ball so it will go in the same direction for 3 seconds.

Response from Expert Dan Andrews:

I need more detail to understand how this works. There is mention of an electromagnet being used, but it is not clear from the picture how this would work.

Can you provide a diagram?
