Hi just need to know if these statements are true or false and why!!!
1. Magnetic field lines indicate the direction of the force on a charged particle passing through the field.
2. Magnetic field lines have no true starting or ending points.
3. When a moving charged particle enters a magnetic field, its kinetic energy is transformed into potential energy.
4. Two parallel wires that are carrying identical currents in opposite directions will repel each other.
5. If Ampere's Law were applied using a loop that encircles a long, straight, DC power cord with two equal and opposite currents, the enclosed magnetic field would be zero.

Hi I just need to know if these statements are true or false and why!! 1. Electric field lines always point from higher to lower potential, meaning that a positive test charge would then seem to "fall" in the correct direction. 2. A student measures the potential between parallel plates A and B, and the meter reading is +30 V. The student concludes that there is a charge on plate B, but none on plate A. 3. If a capacitor...
