- A wire with radius R has a uniform current density. If the current is I, what is the magnetic field at a distance of R/2 from the center of wire? Show your work.In the diagram at right, an uncharged conducting bar is moving with constant velocity v to the left through a region where there is a uniform magnetic field pointing out of the page. What charge distribution will the bar have, as a result of its motion? B out of page The bottom of the bar will have positive charge, and the top of the bar will have negative charge. The bar will remain electrically neutral at all points. The top of the bar will have positive charge, and the bottom of the bar will have negative charge. The right side of the bar will have positive charge, and the left side of the bar will have negative charge. The bar will gain a net positive charge, distributed uniformly along its length. The bar will gain a net negative charge, distributed uniformly along its length, The left side of the bar will have positive charge, and the right side of the bar will have negative charge.What is the expression for the magnetic dipole moment of a small loop of current, with the radius of the loop given by r and the current given by 1? Use I for current, r for radius, pi for T. Use * for multiplication and / for division and collect terms using (). Use ^ for exponent, i.e. for æ" write x^n. You can add an optional tip or note related to the prompt like this. Example: To test this example, the correct answer is R_1*R_2/R_3 Submit Previous bux.bracu.ac.bd
