(a) draw sketch of the magnetic field and path of electron. Determine (b) the magnitude of the B field, (c) acceleration of the electron (m_e= 9.11x10^-31 kg, e=60x10^-19 C).
When a magnetic flux through 5 loops of wire increases by 30.0 T.m², an average current of 40.0 A is induced in the wire. Assuming that the wire has a resistance of 2.5 ohms, (a) over what period of time did the flux increases? (b) If the area of the loop is 0.08 m², perpendicular to the magnetic field and the flux change is only due to change of magnetic field, how much the field changes during this time period ?
