Flux = magnetic field * area
emf = rate of change of flux
emf = B*l*Δw/t = 4*10-2* 2.5*10-2 * 2.5*10-2 / .3 = 8.33 * 10-5 V

A magnetic field is uniform in distribution across a region of space but the strength on the field varies time according to the formula B= 1.5 t^2 where the units have been left off but t is in seconds and is in Tesla. If this field passes straight through a flat wire loop enclosing an area of 0.60 m^2 what the emf induced in this wire loop, at a time of 3 seconds?
7.) (a) A rectangular loop of area 0.1 m2 rotates in a uniform magnetic field of B 2 T. When the angle between the magnetic field and the surface of the loop is 600 and increasing at 1 rad/s, what emf is induced in the loop? (b) The loop has turned further and has stopped with its surface parallel to the magnetic field. If the magnetic field then changes at the rate of 1 T/s, what emf is induced in...
