A scientist measuring the resistivity of a new metal alloy left her ammeter in another lab, but she does have a magnetic field probe. So she creates a 7.5-m-long, 2.0-mm-diameter wire of the material, connects it to a 1.5 V battery, and measures a 4.5 mT magnetic field 1.0 mm from the surface of the wire. Part A What is the material's resistivity? Express your answer in ohm-meters with the appropriate units. ▸ View Available Hint(s)

I, Iz The picture shows two parallel wires where I1 is 19.6 amps, and I2 is 35.5 amps. The location A is in the plane of the two wires and is 30.0 mm from the left wire and 18.4 mm from the right wire. Given the direction of current in each wire, what is the B-field at the location A in micro teslas? (If the B-field points toward make it positive; if it points away from you, make it negative. Give answer as an integer with correct sign. Do not enter unit.) you,
Force between Parallel Wires You have two wires with current running through them (see image below). The wires are a distance d apart.

A simple generator has a square armature 9.0 cm on a side. The armature has 95 turns of 0.59-mm-diameter copper wire and rotates in a 0.800-T magnetic field. The generator is used to power a lightbulb rated at 12.0 V and 25.0 W. Part A At what rate should the generator rotate to provide 12.0 V to the bulb? Consider the resistance of the wire on the armature.
Part A A proton moves through a region of space where there is a magnetic field B-(0.52+0.38) T and an electric field - (3.3-4.4j) × 10³ V/m.

A 550-turn solenoid is 12 cm long. The current in it is 38 A . A straight wire cuts through the center of the solenoid, along a 5.0-cm diameter. This wire carries a 23-A current downward (and is connected by other wires that don't concern us). Part A What is the force on this wire assuming the solenoid's field points due east?
The magnetic field around the head has been measured to be approximately 3.00x10-8 gauss. Although the currents that cause this field are quite complicated, we can get a rough estimate of their size by modeling them as a single circular current loop 16.0 cm (the width of a typical head) in diameter.
