Question

Npole dipole magnet The direction of the circulating eddy cur- rent in the plate is Npole dipole magnet 1. clockwise 4. 2. counter-clockwise. 012 (part 2 of 3) 10.0 points The direction of the induced magnetic field at the center of the circulating eddy current is 1. along the rod away from O 2. into the paper 3. out of the paper 4. parallel to the direction of motion; i.e., above 5 dipole magnet below the arrow in the sketch 5. along the rod toward O above0 Npole dipole magnet 013 (part 3 of 3) 10.0 points The direction of the force which the magnetic field exerts is 6 1. opposite to the direction of swing. 2. along the rod toward the pivot point. 3. into the paper 4. out of the paper 5. along the direction of s below 011 (part 1 of 3) 10.0 points A pendulum consists of a supporting rod and a metal plate (see figure). The rod is pivoted at O. The metal plate swings through a region of magnetic field. Consider the case where the pendulum is entering the magnetic field region from the left

Explanation / Answer

1) The magneticc flux through the pendulum increases as it starts entering the magnetic field and hence eddy currents appear in counter clockwise direction

2) Direction of megnetic field is out of the paper.

3)From right hand thumb rule, direction of magnetic field is along the rod towards the pivot point.
