Please help, will rate lifesaver! This is a web assign questions, so please give me the right significant digits and units.
The figure below shows a current carrying wire located at the origin; the wire carries a current of I = 4.4 A. Points 1, 2, and 3, are all on a circle with radius 15.7 cm which is centered on the origin. (All directions below should be an angle measured counterclockwise from the +x axis to the direction the field points.)
____________T
I For parts (b) - (d), assume the wire carries a current directed out of the page.
(b) What is the direction of the magnetic field generated by the wire at point 1?
____________°
(c) What is the direction of the magnetic field generated by the wire at point 2?
____________°
(d) What is the direction of the magnetic field generated by the wire at point 3?
____________°
II For parts (e) - (g), assume the wire carries a current directed into the page.
(e) What is the direction of the magnetic field generated by the wire at point 1?
____________°
(f) What is the direction of the magnetic field generated by the wire at point 2?
____________°
(g) What is the direction of the magnetic field generated by the wire at point 3?
____________°
