2. A mid-range speaker coil has 30 meters of wire wrapped in 200 loops with 24 mm radius. It is immersed in a magnetic field B=0.50 Tesla radially outward in the white gap). At time t=0 the coil carries a 6.0 Amp current (C) clock-wise. a. Indicate North Pole and South Pole on the (gray) magnet faces. b. Calculate the magnetic Force on the coil (strength and direction!) c. The magnetic field intensity in the gap is NOT uniform ......
1 pts Question 1 Select all of the following that are true about magnets and magnetic fields. the source of magnetic fields is net motion of charged particles the South pole of a bar magnet can be separated from the North pole to make two monopoles like magnetic poles IS and S, or N and N) repel and opposites attract IN and S) □ magnetic field lines always form closed loops magnetic fields are scalars a straight wire with current...
