Question

A long straight wire carrying current I is moving with speed v toward a small circular coil of radius r containing N turns which is attached to a voltmeter as shown The long wire is in the plane of the coil Only a small portion of the wire is shown in the diagram V Part 1 The radius of the coil is 0 02 m and the coil has 11 turns At a particular instant I 4 amperes v 3 7 meters per second and the distance from the wire to the center of the coil x 0 16 m B dt a What is the magnitude of the rate of change of the magnetic field inside the coil You will need to calculate this algebraically before you can get a number Write an expression for the magnetic field due to the wire at the location of the coil Use the dx approximate formula since the wire is very long Remember the chain rule and remember that v dt Save for Later Part 2 i N turns radius r i Voltmeter Save for Later b What is the magnitude of the voltmeter reading Remember that this includes all 11 turns of the coil volts T s Attempts 0 of 3 used Attempts 0 of 3 used Submit Answer Submit Answer
