When the switch is closed in a circuit, the wire between the poles of the horseshoe magnet deflects upward. From this you can conclude that the left end of the magnet is

A) a magnetic dipole.
B) not contributing to the wire's deflection.
C) a magnetic monopole.
D) a south magnetic pole.
E) a north magnetic pole
look up the right hand rule on magnetic field, current, and force
Thanks! I did and originally got E)north magnetic pole but....now I'm second guessing myself that it is D)South magnetic pole..????!?!?!?
The deflection of the wire in a circuit when the switch is closed indicates the interaction between the magnetic field of the horseshoe magnet and the current flowing through the wire.
Given that the wire deflects upward, we can conclude that the left end of the magnet is a north magnetic pole. Therefore, the correct answer is E) a north magnetic pole.
To determine the answer, we need to understand the relationship between the direction of deflection of the wire and the poles of a magnet.
When a current flows through a wire in the presence of a magnetic field, a force is exerted on the wire perpendicular to both the current direction and the magnetic field direction. This is known as the right-hand rule.
In this case, when the switch is closed in the circuit, the wire deflects upward. From this observation, we can conclude that there must be a magnetic field present directed downward. According to the right-hand rule, for the wire to deflect upward, the force must be acting in the opposite direction, which means it is exerted by a south magnetic pole.
Therefore, the correct answer is option D) a south magnetic pole.
