Question

For your backpacking excursions, you have purchased a radio capable of detecting a signal as weak as 1.00 x 10-14 w/m2. This radio has a 2300 turn coil antenna that has a radius of 2.00 cm wound on an iron core that increases the magnetic field by a factor of 200. The broadcast frequency of the radio station is 1500 KHz (a) What is the peak magnetic field strength of an electromagnetic wave of this minimum intensity? (b) What is the peak emf that it is capable of inducing in the antenna? μν (c) What would be the peak emf induced in a straight 1.00 m long wire oriented parallel to the direction of the electric field? HV
