Question
help me with this true false concepts
PHYS2326-TEST II Name ID 2. The magnetic force on a moving charge q is parallel to both its velocity and its magnetic field. 3. A magnetic field will always exerts a force on any charge (or current) present in the field. 4. Two charges of equal magnitude but opposite signs moving in the same direction in the same field will experience magnetic forces in same directions. 5. RC circuits differ from DC circuits because they change over time. 6. According to Faraday's Law, the direction of any magnetic induction effect is such as to oppose the cause of the effect. 7. Maxwell's equations describe the behavior of electric and magnetic fields irn any situation 8. The maximum current available from an individual circuit is limited by the voltage or emf of the circuit. 9. Changing magnetic flux causes an induced electric field. 10. Eddie Currents are electric currents induced within conductors by a changing magnetic field in the conductor. These circulating eddies of current have inductance and thus induce magnetic fields. These fields can cause repulsion, attraction, propulsion, drag, and heating effects 11. Peak and instantaneous quantities in AC circuits obey the same relationships (T F). 12. The AC-rms quantities are the only quantities that correspond to the DC quantities( T/F)
Explanation / Answer
2. False (force perpendicular to velocity and field)
3. False (it exerts a force only on a moving charge)
4. False (They will experience same magnitude of force but the direction of their movement due to the applied force will be exactly opposite to each other)
5. True
6. True (Lenz's law)
7. True (but mainly in vaccuum so you can choose what situation they mention)
