... At that point, the Earth’s magnetic field is 5.0x10-5 T, and the dip angle is 30° to the wire. Estimate the magnitude of the magnetic force on the wire due to the Earth’s magnetic field of at this point. (The dip angle is the angle between the Earth’s magnetic field and the current in the wire. ) ...

... where t0 is equal to the spin time of an electrone and V is equal to the amount of volume, re-circled during the time t0. By inserting the value of N as we have calculated above, we get the formula: (6) i.T=V/t0 (7) (i.T).t0=V We divide both sides of the equation with the time T and get: (8) (i.T).t ...
