Q: A horizontal 6.0m long wire that runs from west to east is in a 0.03-T magnetic field with a direction that is northeast
- If a 4.5A current flows east through the conductor, what is the magnitude and direction of the force on the wire?
Q: Copper metal wire has a linear density of 0.010kg/m. A sample of this wire is stretched horizontally in an area where the horizontal component of Earth's magnetic field of strength 2.0x10^-5T passes through the wire at right angles.
- What current must be applied to the wire if the weight of the entire wire is supported by the magnetic force?
