A 10 A current is charging a 1.0-cm-diameter parallel-plate capacitor. What is the magnetic field strength at a point 2.0 mm from the center of the capacitor?
1.00×10−3T And for the second part I got, 1.60×10−4 T. I'll look how i did it later
aaaahhh noooooo i think this question was on the test and i did wrong
