Based on the information given, which part of Investigation #2 is most likely the independent variable?

• the type of wire

• the number of coils

• the size of the battery

• the strength of the magnet

Which phenomenon is most likely being tested during investigation #1?

• an iron nail is a natural magnet

• an iron nail has to ve used to create an electromagnet

• a small battery has stored magnetism that can be used to attract paper clips

• wire wrapped around an iron nail attached to the poles of a battery will produce a magnetic field

Which phenomenon is most likely being tested during investigation #2?

• the larger the nail is, the more magnetic Forde it will have

• the battery increases the power the there are more coils in the wire

• the magnetic force increases the more coils are wrapped around the nail

• the wire around the nail needs to be thin to make the magnetic force stronger
