consider a flat square coil with 10 turns. The coil is 1m wide on each side and has a magnetic field of 1,0T passing through it. The plane of the coil is perpendicular to the magnetic field: the field points out of the page. Use faraday's law to calculate the induced emf, if the magnetic field is increased uniformly from 1,0 T to 2 T in 20s working : width 1mX10 turns=10. 10x1,0=10. ,
