What are the forces acting on the wire?
Simply put, current-carrying wires create magnetic fields, and they also experience a force when placed in a magnetic field. When two current-carrying wires are parallel to each other, they will exert magnetic forces on each other because they both create magnetic fields.
How are the force on the wire and the force on the magnetic related?
The magnetic force on a current-carrying wire through a magnetic field is given by F = IL x B. When a current is passed through a magnetic field, the magnetic field exerts a force on the wire in a direction perpendicular to both the current and the magnetic field.
What is the force on a wire moving perpendicular to a magnetic field?
If a straight conducting wire is placed in a plane perpendicular to a uniform magnetic field, and is moving in a direction perpendicular to the field, then each charge q in the wire experiences a magnetic force of magnitude F = qvB. The negatively charged electrons will accelerate in response to this force.
How do you find the magnetic force of a wire?
The magnetic force on a current-carrying wire in a magnetic field is given by →F=I→l×→B. For part a, since the current and magnetic field are perpendicular in this problem, we can simplify the formula to give us the magnitude and find the direction through the RHR-1. The angle θ is 90 degrees, which means sinθ=1.
What is the relationship between force and current?
What is the relationship between force and current? Force is directly proportional to current; as the current that passes through the wire increases, so does the magnetic force.
How do you calculate the force of a wire?
The equation for calculating the force on a wire is Force (N) = magnetic flux density (T) × current (A) × length (m) or, in short F = B I L.
On what factors motional emf depends?
The factors on which Motional emf depends are nothing but, the magnetic field and velocity and length of the rod.
Why does current affect magnetic force?
Current is directly proportional to magnetic force for a straight current carrying conductor in a uniform magnetic field. So the force is directly proportional to the size of the current. If the current is increased by five times the force will also increase by five times.
How is magnetic flux related to current?
Sample Answer: The magnetic flux density through a coil is directly proportional to current. When the current increases the magnetic flux density will increase.
