You decide to build a small generator by rotating a coiled wire inside a static magnetic field of 0.30 t. you construct the apparatus by coiling wire into 5 loops of radius 0.18 m. if the coils rotate at 2.0 revolutions per second and are connected to a device with 120ω resistance, calculate the average power paverage supplied to that device.

How would a small bar magnet be oriented when placed at position x?

The ultracentrifuge is an important tool for separating and analyzing proteins. because of the enormous centripetal accelerations, the centrifuge must be carefully balanced, with each sample matched by a sample of identical mass on the opposite side. any difference in the masses of opposing samples creates a net force on the shaft of the rotor, potentially leading to a catastrophic failure of the apparatus. suppose a scientist makes a slight error in sample preparation and one sample has a mass 10 mg larger than the opposing sample. if the samples are 12 cm from the axis of the rotor and the ultracentrifuge spins at 70,000 rpm, what is the magnitude of the net force on the rotor due to the unbalanced samples? ( be thorough on your answer)
