The magnetic field has a particular orientation, which tells you the direction in which a dipole placed in the field will align. The strength of attraction is governed by the magnitude of the magnetic field, measured in SI units of tesla (T). A 1-T magnet is considered strong, and a good electromagnet may generate 5 T. Like the electric field, the magnitude of the magnetic field drops off with increasing distance from the source, but for the magnetic dipole there’s no simple relationship like Coulomb’s law to connect the field strength to distance.
The effect of nonconservative forces is to reduce the total mechanical energy. For the ball projected upward, the drag force isn’t negligible if you throw the ball fast enough. That force is directed opposite to the ball’s motion (whether it’s going up or down), so it does negative work on the ball, reducing its total mechanical energy. In general, the change in mechanical energy ΔE is equal to the work done by nonconservative forces. What Is Power? Power is the rate at which work is done or the rate at which energy is supplied or used.
The analogy continues in that net torque is equal to the rate of change of angular momentum, just as net force equals rate of change of linear momentum. Thus, a rotator with no net torque applied will maintain constant angular momentum. Planets orbit the sun with little change to their 17 18 Classical Mechanics orbits from year to year because there are few objects that can provide enough torque to affect them much. A familiar example of angular momentum conservation is the spinning motion of a figure skater.
