Part (a) To Determine:
Force per metre length of straight wire carrying current 6.40 A placed perpendicular to Uniform magnetic field of 0.90 T.
Answer to Problem 1P
Solution:
Force per metre length of straight wire = 5.76 N/m
Explanation of Solution
Given:
Current I = 6.40 A; Magnetic field B = 0.90 T and Ϙ = 90o
Formula Used:
Calculation:
In order to find the value of force per metre length of current carrying conductor, we have to use the equation,
For force per unit length equation becomes,
Force per unit length =
Putting the values in this equation we get,
Force per unit length =
=
=
Part (b) To Determine:
Force per metre length of straight wire carrying current 6.40A placed 350 to Uniform magnetic field of 0.90T
Answer to Problem 1P
Solution:
Force per metre length of straight wire = 3.28 N/m
Explanation of Solution
Given:
Current I=6.40A; Magnetic field B= 0.90 T and Ϙ=350
Formula Used:
Calculation:
To find the value of force per metre length of current carrying conductor, we have to use the equation,
For force per unit length equation becomes
Force per unit length becomes =
