A student created an electromagnet out of a D 1.5 volt battery, a nail and some wire. What are ways he/she could boost the strength of the electromagnet? Select all that are correct.
Sasha dropped a magnet on the sidewalk. Now it no longer attracts paper clips. Why?
Draw magnetic field lines around the two bar magnets pictured below.
An electromagnet with 50 coils can pick up 12 paper clips and an electromagnet with 200 coils can pick up 48 paper clips, How many paper clips do you think a magnet with 100 coils could pick up?
In the Electromagnet lab, 20 coils picked up 10 paper clips. A paper clip weighs .003 pounds. A Nissan Altima Car weighs 3,100 pounds. Using what you just found, how many coils would it take to lift up the car?
