Magnetic Flux and Forces

During this lab we conducted experiments with magnetism, mainly focusing on magnetic flux and magnetic forces. We initially did a quick experiment with a bar magnet and compass, we used the compass tip as direction vectors that we plotted

 

Using metallic shavings we observed magnetic field lines similar to electric field lines but they are continuous. Sum B*da=0 gausses law for magnetic fields says that there are as many field lines coming in as leaving. They leave the north pole of the magnet bar and enter into the south pole. They have yet to observed as a monopole. 

 

 

Here we had a magnetic field produced by a permanent magnet with a current moving from right to left using the right hand rule. We expected to see a force move the copper pipe in our observation direction, which it did, thus confirming the formula for force in a magnetic field F=qv*B.

 

 

 

Here with our given information and the fact that  the pole had translational and rotational motion we had to utilize kinematics and the equation we found earlier in the day to find the value of the magnetic field 2.5 *10^-3 Telsa.

 

 

Next, we derived a proportionality between the magnetic field and the current present in the conductor.

 

Here we looked at torque and what factors contributed to a magnetic field causing moments. Using a rectangular square derived a relationship I that expressed torque as IAxB where we cross the factor Mu= IA with the mabgneticfield B.
