Cirquit homework 1. The problem statement, all variables and given/known data A wire hangs loosely in a magnetic field, it is free to move up or down, the field is 90° on the wire. So the wire gets a charge of 2C over a period of time that is not stated. find the distance it moves during this time. Wire has length 0,25cm, mass m, field is 0,4 T. 2. Relevant equations F=ma, F=b*q*i magnetism. 3. The attempt at a solution F=ma=b*I*i=b*2C/t*l <-> a=h/t^2=b*2C/t*l <-> h = distance moved = (b*2c*l)*t. All I can get is a function of time how to I get a numeric answer that is not a function? I have a possible solution, though. Magnetic force is excerted over the given time t so t shortenes out and the charge unit coloumb too I guess? so I'd end up with the number h = 0,4 * 2* 0,25 m= 20 centimeters moved. Since all the units make it add up, I am not sure if this is correct though. Nevermind I have solved it.
