- A long wire carries current towards east. A positive charge moves westward and just north from the wire. What is the direction of the force experienced by this charge?Use the data from the table to determine at what approximate distance from the wire the magnetic field strength would equal that of a refrigerator magnet. Current= 11ATwo long straight current-carrying wires are lined up parallel to one another in vacuum at a distance ?d. Currents of ?1I1 and ?2I2 flow through the wires, both in the same direction generating the field of ??BM at a midpoint between them. Write down an expression for ??BM in terms of the currents running in each of the wires. Assume vacuum permeability ?0=1μ0=1. Please use "*" for products (e.g. B*A), "/" for ratios (e.g. B/A) and the usual "+" and "-" signs as appropriate. For 1?∗?1A∗B use 1/(A*B). For Greek letters such as ?λ or ?π use lambda and pi. Please use the "Display response" button to check you entered the answer you expect.
