Renaldo and nasreen build an electromagnet by wrapping a wire around a nail and connecting the wire to both terminals of a battery. when they test the electromagnet, it can pick up 6 paper clips. their teacher wants all groups to pick up at least 10 paper clips. what could renaldo and nasreen do to increase the number of paper clips their electromagnet picks up?

question 9 options:

a. increase the number of loops of wire around the nail

b. make the wire longer

c. remove the nail from the center of the wire

d. spread the loops of wire apart on the nail so they do not touch

a.increase the number of loops of wire around the nail

Explanation:

An electromagnet is created when a wire is wrapped around a conductor that is a nail and current is passed through. The nail would act like a magnet. The nail would attract more number of clips if the magnetic strength of the magnet that is the of the nail can be increased. In order to increase the amount of magnetic field strength, the amount of current should be increased or number of turns can be increased. Thus, from the given options, the most suitable one is a.increase the number of loops of wire around the nail

c. newton's third law of motion

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
