Title: A constant magnetic field is applied perpendicular to the plane of a square, sin Post by: ppk on Feb 25, 2012 A constant magnetic field is applied perpendicular to the plane of a square, single-turn coil with each side equal to 15 cm. If the area of the coil decreases at a rate of 0.20 m2/s, an emf of 20 mV is induced in that coil. What is the strength of the magnetic field applied to the coil?
A) 0.10 T B) 0.20 T C) 0.30 T D) 0.40 T E) 0.50 T Title: Re: A constant magnetic field is applied perpendicular to the plane of a square, sin Post by: duddy on Feb 26, 2012 Content hidden
