|||A particle with a charge of +/-q= C enters a region of magnetic field as shown here, with a speed of
v= m/s .
The B-field has a strength of B= Tesla . When the particle enters the B-field region, it is seen to sweep out a semi-circle, and hit the edge of the device a distance x= cm to the right of where it entered.
|||Two wires, on carrying a current I1= Ampere and the other carrying I2= Ampere are shown. Both currents are in the same direction, into the screen.|
|||Two current carrying wires are shown here. They carry currents in opposite directions, in this case, one out of the computer screen and the other into the screen.|
|||Two current carrying wires are shown here. They carry currents in the same direction, in this case, out of the computer screen.|
|||A wire carrying a current I1= A is shown here. Right next to it is a loop of wire carrying a current I2= A .|
|||A bar of mass m= kg can slide on two bare wires along a horizontal table. A current
I= A is maintained in the wires and bar. The whole system is immersed in a vertical, downward magnetic
field, as shown.
What is the acceleration of the bar? Will it move to the left or right?
|||A bar is on an inclined pair of wires, at \theta= degrees as shown here.
The bar has a mass of m= kg and slides freely on the wires that are L= m apart. A magnetic field of strength B= Tesla is pointed straight down. What current is needed to run through the system so that the bar does not slide down the incline?
