A bar magnet is inside a closed cubical box.Magnetic field lines pointing outward from the box produce positive flux, and those pointing inward produce negative magneticflux. (a) Is the total magnetic flux through the surface of the boxpositive, negative, or zero? (b) Choose the best explanation fromamong the following:I. There are more outward magnetic field lines because the magnet is inside the box.II. The magnet draws field lines inward toward itself, producingmore negative flux.III. The same number of magnetic field lines leave the box asenter it.
Suppose a uniform magnetic field is perpendicular to the x 11-in. page of your homework and a rectangular metal loop lies on the page. The loop's sides line up with the edges of the page.

1. Take e/m to be the accepted value of 1.76-10¹¹ C/kg. For a plate voltage of 100 volts and a circular beam of radius 3.0 cm, what would you expect the required magnetic field B to be? Assume that the above magnetic field is produced by two Helmholtz coils, and assume that each coil has 119 turns, a radius of 106 mm, and a separation of 106 mm. What cur- rent I is required to achieve the expected magnetic field?
(Hand by written ans.)A circular loop (10 turns) with a radius of 29 cm is in a magnetic field that oscillates uniformly between 0.95 T and 0.45 T with a period of 1.00 s. a. How much time is required for the field to change from 0.95 T to 0.45 T? b. What is the cross-sectional area of one turn of the loop? c. Assuming that the loop is perpendicular to the magnetic field, what is the induced emf in the loop? I have a test and i am revising and I got 2 answers for this question. could you please explain each step thoroughly for me to understand.
