ABC is a triangular frame made out of a metallic wire.
BD is a median of the triangular frame joining the vertex
B to the side
AC, (Also made of the same metallic wire). It is known that
AB=6 cm, BC=8 cm and
AC=10 cm. The cross-sectional area of the wire is
1 mm2 and its resistivity is
24 nΩm. The triangle
ABC lies in a cylindrical region of magnetic field such that the intersection of the surface of the cylinder with the plane containing the frame forms the circumcircle of triangle
ABC. The magnetic field in the region varies at the rate of
0.263 T/s. What is the magnitude of the induced current in
mA in the median
BD of the frame?
