Consider a system consisting of three current-carrying wires, one very long straight wire and two coiled wires as shown in the figure. The three wires are insulated from each other and there is no friction between the wires. R = 70 cm Given vacuum permeability is u0 = 4π x 10^ - 7 * T * m / A A. The magnitude of the magnetic field at the point P by the current l₁ = 4 A is..... uT B. So that the magnitude of the magnetic field at point P by current I1 is equal to the magnitude of the
Please solve the all sub parts ... I'm needed max in 20 please and no reject I'm needed the answer thank u
Consider a system consisting of three current-carrying wires, one very long straight wire and two coiled wires as shown in the figure. The three wires are insulated from each other and there is no friction between the wires. R = 70 cm Given vacuum permeability is u0 = 4π x 10^ - 7 * T * m / A
A. The magnitude of the magnetic field at the point P by the current l₁ = 4 A is..... uT
B. So that the magnitude of the magnetic field at point P by current I1 is equal to the magnitude of the magnetic field by current , then the ratio I2/I1 is...
C. For and according to problems a and b while I3=I2 then the magnitude of the magnetic field at point P by all current-carrying wires is... uT
D. If I3 = 2l2 , then the two wires are circular.... Write your answer in numbers: -1 if the two wires are moving away from each other, 1 if the two wires are close to each other, and 0 if the two wires are at rest
