Homework Answers
Magnetic fields affect charges only when charges are in motion.
There is no magnetic force on static charges. When charges are stationary, their electric fields do not affect magnets.
But, when charges move, they produce magnetic fields that exert forces on other magnets.
So correct answer is- option A. (Only when charges are moving.)

An implication of the Maxwell Equation V x B = 11,J is that O magnetic field lines form closed loops. O magnetic fields exert forces on moving electric charge. O magnetic charges come in discrete units. O magnetic field lines begin on north poles and end on south poles. O there are no magnetic monopoles.
Magnetic Fields and Forces on Point Charges
Positive point charges q = 9.00 μC and q'= 4.00 μC are moving relative to an observer at point P, as shown in the figure . The distance d is 0.120 m, v = 4.40×106m/s, and v'= 8.80×106 m/s.Part A:When the two charges are at the locations shown in the figure, what is the magnitude of the net magnetic field they produce at point ?Part B:What is the magnitude of the electric force that each charge exerts on the other?Part...

Moving charges will produce a local magnetic field, but the reverse is also true a changing magnetic field will similarly induce charges to move (ie. produce current). Consider a magnet moving into a coil of wire: A spinal coil of wire with many closely-spaced tums this is called a solenoid is connected to a micro-ammeter as shown in the diagram above. As the magnet moves into the coil, any induced current will be measured by the micro-ammeter. Question On the...
