- A coil formed by wrapping 55 turns of wire in the shape of a square is positioned in a magnetic field so that the normal to the plane of the coil makes an angle of 36.0° with the direction of the field. When the magnetic field is increased uniformly from 200 µT to 600 µT in 0.400 s, an emf of magnitude 80.0 mV is induced in the coil. What is the total length of the wire? mc. What is the resistance of the coil given that the diameter of the wire is 2.00 mm? (Recall, resistance of wire is given by R = ρL/A, where ρ is the resistivity of the metal, L is the length of the wire, and A is the cross-sectional area.)A helicopter (see figure below) has blades of length 2.80 m; extending out from a central hub and rotating at 3.40 rev/s. If the vertical component of the Earth's magnetic field is 50.0 μT, what is the magnitude of emf induced between the blade tip and the center hub? mV Sascha Hahn/Shutterstock.com
