If you put a small magnet, like a compass, in a magnetic field, the magnet
will
O swing randomly
Obecome less magnetized
O eventually line up parallel to the magnetic field lines
O line up in a direction perpendicular to its magnetic field lines

How do you tell if someone actually cares about you? and just say they do?

Positrons are spontaneously emitted from the nuclei of

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
