4 X 10^-4/2^1/2
b) A conductor located at z=0, x=4m carrying a current of 12.0A? Hmm, talk about being in the right place at the right time! Now, you want to find the uniform...uniform what? Are we talking about a dress code for the conductor or something else? Oh, you meant to say uniform magnetic field in the region! Silly me! Well, to calculate that, we can use the formula F = BIL once again. Since we know the magnetic field, force, and current, we can rearrange the formula to solve for B. Unfortunately, you forgot to mention the force acting on the conductor, so I'll have to leave you hanging without an answer. But hey, maybe a good laugh can make up for it!
F = I * L * B * sin(theta)
Where:
F is the force on the conductor
I is the current in the conductor
L is the length of the conductor
B is the magnetic field
theta is the angle between the direction of the current and the magnetic field
In this case, the length of the conductor (L) is given as 0.30 m and the current (I) is given as 5.0 A. The magnetic field (B) is also given.
Since the conductor is carrying current in the direction of the magnetic field, the angle between them is 0 degrees. So, sin(theta) will be 0.
Therefore, the force on the conductor is 0 N.
b) The force on a conductor is given by the formula:
F = I * L * B * sin(theta)
Given that the force on the conductor is 8.0 N, the length of the conductor (L) is 2.5 m, and the current (I) is 12.0 A, we can rearrange the formula to solve for the magnetic field (B):
B = F / (I * L * sin(theta))
Since the force and the direction are known, we can substitute these values into the formula.
Plugging in the values, we get:
B = 8.0 N / (12.0 A * 2.5 m * sin(theta))
Since the force is in the positive x-direction and the magnetic field is in the positive z-direction, we can say the angle theta is 90 degrees.
Therefore, sin(theta) = sin(90) = 1.
Plugging this into the equation, we get:
B = 8.0 N / (12.0 A * 2.5 m * 1)
Simplifying this, the uniform magnetic field is:
B = 8.0 N / 30.0 A*m
B = 0.27 T
So, the uniform magnetic field in the region is 0.27 T.
F = BILsinθ,
where F is the force on the conductor, B is the magnetic field strength, I is the current in the conductor, L is the length of the conductor, and θ is the angle between the current direction and the magnetic field direction.
a) In this case, you are given:
I = 5.0A (current)
L = 0.30m (length of conductor)
B = ? (magnetic field strength)
θ = 0 degrees (the current is parallel to the magnetic field)
To find the force, we first need to determine the magnetic field strength. Since we are given the force and the current is parallel to the magnetic field, we can rearrange the formula to solve for B:
B = F / (ILsinθ)
Substituting the given values, we have:
B = F / (I * L * sinθ)
B = F / (5.0A * 0.30m * sin(0 degrees))
B = F / 0 (since sin(0) = 0)
Since the denominator is zero, the magnetic field strength (B) cannot be determined without additional information.
b) In this case, you are given:
I = 12.0A (current)
L = 2.5m (length of conductor)
F = N (force on the conductor)
θ = 90 degrees (angle between the current direction and the magnetic field direction)
Again, we can use the formula F = BILsinθ to find the magnetic field strength (B) and the uniform magnetic field between the conductor:
B = F / (ILsinθ)
B = N / (12.0A * 2.5m * sin(90 degrees))
B = N / (30.0A * sin(90 degrees))
B = N / 30.0A
So, the uniform magnetic field in the region is N / 30.0A, where N is the force on the conductor.
