Magnetic Force Characteristics
Advertisements
Description:
To apply magnetic force on a charge, the charge should be in motion as magnetic force affects only moving charge while stationary charge is unaffected.
Magnetic force cannot change the magnitude of velocity of charge.
Magnetic force changes the direction of charge traveling through a magnetic field and attempts to move the charge in a circular path in the field.
Difference between Magnetic and Electric Field
| 1. | Force within the magnetic field is given by - F =→qV →B → | Force within the electric field is given by - F =→qE → |
| 2. | Applicable on moving charge only. | Applicable on stationary as well as moving charge. |
| 3. | It cannot change the magnitude of velocity (speed) because its component along v =→ is Zero. | It increases / changes the magnitude of velocity (speed increase). |
| 4. | It can change the direction of moving charge. | There is no change in direction. |
