(a) Negative. From the right hand rule we will be able to find the directions as well as the force to be normal to current and magnetic fields. …
What will be the force if the flow of electric current is parallel to the magnetic field?
If the flow of electric current is parallel to the magnetic field, the force will be? Explanation: Force is a cross product. … If two quantities are parallel to each other, the angle between them is zero. Sin(0) is zero, hence force is zero.
What happens if the current is parallel to the magnetic field?
If the current direction is parallel to the magnetic field, then there will no force on the conductor exerted by the magnetic field.
Can magnetic field line be parallel to the direction of current flow?
Answer: nope they are always opposite in the direction of current…..
When the wire is moved parallel to the magnetic field what would be the direction of the flow of current?
The current flowing through the two parallel conductors of the loop are in opposite directions as the current through the loop exits the left hand side and returns on the right hand side. This results in the magnetic field around each conductor inside the loop being in the “SAME” direction to each other.
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.
What is the expression for force in a current carrying conductor *?
The force on a current-carrying wire in a magnetic field is F = IlB sin θ.
Why is there no force when current and magnetic field are parallel?
The simple reason is that by definition, electromagnetic waves travel perpendicular to one another and therefore exert no force on the other. If you have a current traveling north, but a magnetic field traveling east, due to the mathematical cross-product the force will cancel.
Why no force acts on a current carrying conductor when it is parallel to the magnetic field?
Answer: No force acts on a current carrying conductor when it is placed parallel to the magnetic field. For example:- You can see in a DC motor, the coil which is parallel to the magnetic field lines does not experience a force, but the coil which is perpendicular to the magnetic field lines experiences.
Does the current carrying conductor experience some force when kept parallel to the magnetic field?
A current carrying conductor experiences a force in a magnetic field.
How will you relate the magnetic force to magnetic field lines?
Since magnetic forces act at a distance, we define a magnetic field to represent magnetic forces. … As shown in Figure 1, the direction of magnetic field lines is defined to be the direction in which the north end of a compass needle points. The magnetic field is traditionally called the B-field.
What is the direction of the magnetic lines of force inside the magnet?
∴ The magnetic lines of forces inside a bar magnet are from south-pole to north-pole of the magnet.
What is magnetic lines of force in physics?
Magnetic Lines of Force is a an imaginary line representing the direction of magnetic field such that the tangent at any point is the direction of the field vector at that point.
What happens when electric current flows through a wire?
In fact, when electric current flows through a conductor, it generates a magnetic field around the conductor. The magnetism resulting from flowing electric charges is called electromagnetism. stronger magnetic field, you can wrap the coils around an iron rod (or other iron object).
When conductor is moving in magnetic field it develops the?
(A): An induced current develop in a conductor moved in a direction parallel to the magnetic field. (R): An induced current is developed when the number of magnetic lines of force associated with conductor is changed.
What was the result of the opposing magnetic force and the magnetic field on the flow of the current?
When a magnetic field is present that is not parallel to the motion of moving charges within a conductor, the charges experience the Lorentz force. … This opposes the magnetic force, eventually to the point of cancelation, resulting in electron flow in a straight path.
