- A current /= 40.0 A flows through a strip of metal. An electromagnet is switched on so that there is a uniform magnetic field. If the width of the strip is 2.70 cm, the magnetic field is 0.190 T, and the Hall voltage is measured to be 3.10 µV, what is the drift velocity of the carriers in the strip? хх X X' X X- X Metal strip mm/sWhich of the following is true, and which of the following is false? If a bar magnet, with its north pole facing the gap of a copper pipe, is forced to change polarity after induction, the bar magnet falls faster. An induced magnetic field has predictable electric field vectors. Alternating current, developed by Thomas Edison, is a stable electric source incapable of traveling long distances. Lenz’s Law dictates where an induced current moves during induction. An electrostatic electric field does nonconservative work.A coil with 200 turns is placed in a uniform magnetic field with a flux of 0.628 mT/m². Then the magnetic field changes till the flux become 0.125 mT/m² in 3 s and the magnetic field changes its direction. If the plane of the loop is perpendicular to the direction of the magnetic field calculate the electromotive force generated.
