Magnetism problem for General Physics 2!!
Suppose the rod in the figure has mass m= 0.40kg and length 20cm and the current through it is I= 40A .
(Intro 1 figure)
If the coefficient of static friction is us= 0.55, determine the minimum magnetic field (not necessarily vertical) that will just cause the rod to slide. Give the magnitude of B.
I am not really sure what equations I am supposed to use for this problem..I don't really know how to get started...can someone help me please!!!
I think F=ma....using the static coeff. us=.55
Maybe..F=qv x B
or F = qvB sin (theta)
