A generator uses a coil that has 210 turns and a 0.20-t, Ask an Expert

Academics

Q1. A 3.988x10^-26 kg mass particle with negative -1.44x10^-18 C charge is initially moving at 50m/s parallel to a wire with 18A current going to the right. The permeability of free space is 4*(pi) x10^-7. Find out the magnitude of the magnetic force acting on the negative particle at point p.

Q2. A generator uses a coil that has 210 turns and a 0.20-T magnetic field. The frequency of this generator is 60.0 Hz, and its emf has an rms value of 120 V. assume that each turn of the coil is a square (an approximation), conclude the length of wire from which the coil is made.
