Dylan puts two magnetic toy trains very close to each other on a track. What will happen next, and -hy?
a
The trains will not move because the magnets are not touching.
b
The trains will move closer to each other because the magnetic force will pull the trains
together
с
The trains will move away from each other because the magnetic force will push the trains
apart.
d
The trains will move away from each other because the magnets are not touching.

Porque crees que el agua no podia subir mas de 10 m de altura con ese tipo de bomba

Based on this activity, is kinetic energy always transformed into potential energy?

Irrigation channels that require regular flow monitoring are often equipped with electromagnetic flowmeters in which the magnetic field is produced by horizontal coils embedded in the bottom of the channel. a particular coil has 100 turns and a diameter of 6.0 m. when it's time for a measurement, a 4.5 a current is turned on. the large diameter of the coil means that the field in the water flowing directly above the center of the coil is approximately equal to the field in the center of the coil. the field is directed downward and the water is flowing east. the water is flowing above the center of the coil at 1.5 m/s . what is the magnitude of the field at the center of the coil? what is the direction of the force on a positive ion in the water above the center of the coil? what is the magnitude of the force on an ion with a charge +e?
