SOLENOIDS
A solenoid is made out of a current-carrying wire which is coiled into a series of turns. A 50 loop solenoid of radius 4cm is placed in a magnetic field directed perpendicular to the magnetic normal .The coil carries a 480 mA current and the magnetic field has a strength of 75mT.
Calculate the maximum torque on the current loop. Show the direction of the torque relative to the wire( (Show drawing/figure for full credit).
A package in an airplane moving horizontally at 275 m/s is dropped while the altitude is 766 meters. How far forward from the spot over which it was dropped does the package land.
