Along wire carrying a 6.0 a current perpendicular to the xy-plane intersects the x-axis at x=−2.2cm. a second, parallel wire carrying a 2.6 a current intersects the x-axis at x=+2.2cm. part a. at what point on the x-axis is the magnetic field zero if the two currents are in the same direction?
part b. at what point on the x-axis is the magnetic field zero if the two currents are in opposite directions?

(A). The magnetic field is zero at 0.8 cm.

(B). The magnetic field is zero at 5.56 cm.

Explanation:

Given that,

Current in first wire I = 6.0 A

Current in second wire = 2.6 A

Distance

Distance

(A). We need to calculate the magnetic field

If the currents are in the same direction

The magnetic field is in both wires

Put the value into the formula

Put the value into the formula

The point where the magnetic field is zero

The magnetic field is zero at 0.8 cm.

(B). We need to calculate the point where the magnetic field zero

If the currents are in the opposite direction

The magnetic field is in both wires

Put the value into the formula

Put the value into the formula

The point where the magnetic field is zero

The magnetic field is zero at 5.56 cm.

Hence, This is the required solution.

b

explanation:

bc its just b

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
