Sharks are known to detect electric fields down to 0.5 μV/m. When they swim at the velocity v through a magnetic field, B an electric field, E = v Bsing is generated, where is the angle between the velocity and the magnetic field. Assume a shark (width at the head w= 0.14 m) swims at the velocity 3.0 m/s at a right angle through the Earth's magnetic field, 8 = 5.10-ST. Determine the electric field generated in this motion. E = v/m What voltage develops across the width the shark's head? AV = V. The shark can detect this, and it's one way for it to gauge its speed through the water.
