Either of them is. 1/(the other one). That's 'C' .
The magnetic field and force is weakest in the center of the magnet. The correct answer is C.
Answer:

Explanation:
the relation between current, voltage and resistance in an electrical circuit is given by Ohm's law:

where V is the voltage, I is the current and R is the resistance. In this problem, the current is I=2 A, the voltage is V=120 V, therefore we can arrange the previous equation and find the resistance:

Answer:
Yes
Explanation:
Heat affects the magnets because it confuses and misaligns the magnetic domains, causing magnetism to decrease
