Finding the poles of different magnets version 2: Application Experiment

Aim

Find the poles of different magnets using two independent methods and then check your answer.

Prior Knowledge

Magnetic fields
Magnetic force
Electromagnetic Induction
Lenz's rule

Description of the Experiment

A harder version than the previous one. Watch the first video and determine the poles of both the horseshoe magnet and the bar magnet. Then check your results with the second video

Addtional Information

Draw a picture of the apparatus in the first experiment with the wire and the horseshoe magnet, determine the direction of the current in the wire and record the direction of the force exerted by the magnet on the wire and then determine the poles of the magnet. For the bar magnet, galvanometer and coil, first use the galvanometer and battery to relate direction of the current in the circuit to the deflection of the galvanometer needle. Then observe the current induced in the coil by the moving magnet. Find the direction of the current, then find the direction of the magnetic field associate with this current and then use Lenz's law to determine the poles of the magnet.
