Motors

During this lab we experimented with an electric motor that utilized copper coils, magnetic fields, and current to cause torque on axle of the motor. The motor rotates 180 before  becoming an open circuit and letting the inertia of the armature close the circuit again and thus creating a torque.

We were tasked with creating our own motors using the ideas of coils, commutator's, and current. Next, we wrapped coils of copper for current to go through, sanded one end completely off and the other only partially to act as our commutator, then used a 3V source for our current.

This was our set up for our motor

 

 

 

 

We explored how  lines of current magnetic fields interacted. We found that they could be calculated using the principle of superposition, meaning equal and opposite currents magnetic fields would cancel out, while equal and same direction would be additive.
