Figure a shows a circuit consisting of an ideal battery with emf = 6.00V a resistance
Question:
Figure a shows a circuit consisting of an ideal battery with emf ξ = 6.00μV a resistance R, and a small wire loop of area 5.0 cm2. For the time interval t = 10 s to r = 20 s, an external magnetic field is set up throughout the loop. The field is uniform, its direction is into the page in Figure a, and the field magnitude is given by B = at, where B is in teslas, a is a constant, and t is in seconds. Figure b gives the current i in the circuit before, during, and after the external field is set up. The vertical axis scale is set by is = 2.0 mA. Find the constant a in the equation for the field magnitude.

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. The video shows the practical implications of magnetic force around different objects.
