Magnetic Force Body Diagram. Assume that the centre of mass c of the system is the centre of a circular orbit for each black hole as shown in the diagram. The object or body is usually shown as a box or a dot.
Contact forces act when objects are. Contact and non contact field forces. An example of a free body diagram is shown at the right.
For part a since the current and magnetic field are perpendicular in this problem we can simplify the formula to give us the magnitude and find the direction through the rhr 1.
The magnitude of the magnetic force is given by f ilbsinθ. Here f 120 a350 m0200 tsin90 840 n. It is generally customary in a free body diagram to represent the object by a box and to draw the force arrow from the center of the box outward in the direction that the force is acting. B w 0 f where w is the force of gravity acting on the magnet.
