Emf induced in rod traveling through magnetic field. An emf induced by motion relative to a magnetic field is called a motional emf. This is represented by the equation emf = lvb, where l is length of the object moving at speed v relative to the strength of the magnetic field b. Google classroom facebook twitter.

When a helicopter lands on the ground, it enters the earth’s magnetic field. Based on faraday’s law, the blades of. (b) yes, an excess amount of charge is built up at the ends of the rod when key is open. When key is closed, the excess charge is maintained by the continuous flow of current. (c. Motional emf is the emf induced in a conducting rod when it moves in a region of magnetic field. Motional emf is calculated by e = v b l where b is the magnetic field and l is the length of the rod and v is the velocity of rod perpendicular to the length of the rod. The magnetic flux through the open surface is therefore. (9. 4. 1) φ m = b l x. Since b and l are constant and the velocity of the rod is v = d x / d t, we can now restate faraday’s law, equation 13. 2. 2, for the magnitude of the emf in terms of the moving conducting rod as.
