A student uses a magnet to place a picture on the refrigerator door. Which statement explains how the magnet is able to stick to the refrigerator without directly touching it?
1-10
for evebody lookin for dis its
1-The magnet’s magnetic field can act at a distance, and influence the metal of the door through the picture.
2-battery, iron nail, wire
3-How is the strength of an electromagnet affected by the voltage of the battery?
4-Generator
5-More coils of wire increases the strength of the electromagnet
6-Magnetic fields can be observed between objects that are not touching
7-Get a larger magnet with a larger magnetic field
8-Which objects react to a magnetic force?
9-Add batteries to increase the voltage, and decrease the space between the coils of wire.
10-The bolt will lift more paper clips, because more coils of wire produces a stronger magnetic field.
