A metal bar is being pushed to the right along a U shaped conducting rail in the presence of a constant magnetic field. This induces a clockwise current as shown in the figure below. The green arrow represents the pushing force. In which direction does the original magnetic field point? - Select one: a. Up b. Down c. Into the screen d. Out of the screen e. To the right

RS ws Inside 1. You have two parallel metal rails that are connected by a 32 resistor as shown in the figure on the right. You slide a metal bar onto the rails so that the two rails, the bar, and the resistor make a complete circuit. The bar has a length of 0.16 m. You place this apparatus inside a uniform magnetic field with a strength of 0.57 T that points into the page. You pull the bar to...

only need part B answered please.
A one-turn current loop, in the shape of an equilateral triangle with sides a, lie in the x-y plane and moves with velocity v in the +x direction. (Assume that some external force that is not shown in the figure keeps the velocity constant.) The loop has a net resistance of R. It passes through a region of constant, spatially uniform magnetic field B that points in the -z direction (into the screen) and...

A conductive rod is placed on a U-shaped rail which are then placed in a uniform magnetic field (out of the page) of magnitude 0.500 T. The conductive rod is pulled at a constant speed of 0.500 m/s. The U-shaped rail has negligible resistance and dimension l = 0.440 m as shown in the figure. The light bulb has a resistance of 2.00 Q and the conductive rod has a resistivity of 2.00 x 10-30m and a cross-sectional area of...

x=L The rail gun consists of two thick conducting rails connected to a power supply and there is a magnetic field assumed to be uniform and constant in the direction shown. A short conducting bar that is to be (or carry) the projectile is placed across the bars at x -0. The current flows through the bars as shown. The magnetic force on the bar causes it...

Magnetic levitation A metal rod of length w = 15 cm and mass m = 85 grams has metal loops at both ends, which go around two metal poles (see the figure). m = mass of red ------ ------- The rod is in good electrical contact with the poles but can slide freely up and down. The metal poles are connected by wires to a battery, and a current I = 3 amperes flows through the rod. A magnet supplies...
