Question

A circular coil that has N = 210 turns and a radius of r = 9.00 сm lies in a magnetic field that has a magnitude of Bo = 0.0600 T directed perpendicular to the plane of the coil. What is the magnitude of the magnetic flux Og through the coil? OB = 0.321 The magnetic field through the coil is increased steadily to 0.180 T over a time interval of 0.515 s. What is the magnitude El of the emf induced in the coil during the time interval? |E| = 0.43

Answer 1

Given N- 210 - 9.00cm z o.ogm. Bod. v 600T Formula for magnetic ther – de = NBA - 8 = 210 x 0.0600 x 6.09 2. - = 0.321 (Aus) If magnetic field is increased let new magnetic field B,= 0.180 T i wew flux d = NBA -) ! = 2107 0.180 x + $0.09? -) != 0.962 13

. Change in flux d&- - Co. - d $ = 0.962 -0.32/ =) d = 0.641 Time interval given, dt- o.siss. Formula for induced emf - E= 14 - - - 0.641 Volts. TE - 1.245 volts Aus)
