A wire is connected to batteries (not shown), and current flows through the wire. The wire lies flat on a table, and you are looking down on it from above. The wire is laid on top of a compass,
resting about 3 mm above the needle. The distance d is 3.5 cm. The compass needle deflects 11 degrees from North, as shown. At this location the horizontal component of the Earth's magnetic
field is 2e-5 tesla.
What is the direction of the magnetic field at location A, midway between the wires, due to the current in the wire?
---Select---
What is the approximate magnitude of the magnetic field at location A, due to the current in the wire?
