# When current is parallel to magnetic field then force?

Contents

Answer. Explanation: When current is parallel to magnetic field, then force experience by the current carrying conductor placed in uniform magnetic field is (a) Twice to that when angle is 60° (b) Thrice to that when angle is 60° (c) zero.

## What happens when conductor is parallel to magnetic field?

When the conductor is perpendicular to the magnetic field, the force will be maximum. When it is parallel to the magnetic field, the force will be zero.

## When current is parallel?

A parallel circuit has two or more paths for current to flow through. Voltage is the same across each component of the parallel circuit. The sum of the currents through each path is equal to the total current that flows from the source.

## What is the magnitude of force exerted on a current carrying conductor placed in a magnetic parallel to the magnetic field?

Answer. Answer: Thus, the magnitude of the force on a current-carrying conductor in a magnetic field varies with the angle between the direction of the length of the conductor and the direction of the magnetic field. Hence, the magnitude of force is zero when the conductor lies parallel to the field.3 мая 2020 г.

## Will there be a force on a current carrying wire in a magnetic field if the current and fields are parallel?

There is no motor effect force if the current and magnetic field are parallel to each other. The direction of a motor effect force can be found using Fleming’s left-hand rule. … the thumb shows the direction of the motor effect force on the conductor carrying the current.

## What is Fleming’s left hand rule?

Fleming’s Left-Hand Rule is a simple and accurate way to find the direction of force/motion of the conductor in an electric motor when the magnetic field direction and the current direction are known.

## How will this force change if current in the conductor is increased?

A larger current in the conductor will result in a larger force acting on it if the strength of the magnetic field is kept constant, as shown in Figure. The magnitude of the force on a current carrying conductor increases when the strength of the magnetic held is increased.

## Is current constant in parallel?

Components connected in parallel are connected along multiple paths so that the current can split up; the same voltage is applied to each component. … In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents flowing through each component.

## What happens to current in a parallel circuit?

The current in a parallel circuit splits into different branches then combines again before it goes back into the supply. When the current splits, the current in each branch after the split adds up to the same as the current just before the split.

## Why is current same in series?

The amount of current in a series circuit is the same through any component in the circuit. This is because there is only one path for current flow in a series circuit.

## What is the cause of magnetic field inside a human body?

Answer. The human body is a good conductor of electricity. Under the influence of an alternating current, the electric charges inside the body move back and forth at the same frequency as the field (60 Hz). In other words, the field produces weak electric currents in the body.

## What is the difference between bar magnet and electromagnet?

The key difference between bar magnet and electromagnet is that the bar magnet has a permanent magnetic field whereas the electromagnet has a temporary magnetic field. A magnet is a material that can produce a magnetic field. The magnetic field is invisible. … Ferromagnetic materials can be used to make bar magnets.

## When the force acting on a current carrying conductor in a magnetic field is maximum and minimum?

The force on a current carrying wire is maximum only when the wire is perpendicular to the direction of magnetic field. It is minimum, that is, no force acts on the conductor when it is parallel to the magnetic field.

## Do magnetic fields cancel each other?

It’s true that along a line exactly between the (infinitely long) wires, the magnetic field will cancel. [Recall that the field on wire 1 due to wire 2 is s B=mu0*I2/(2pi*r) and corresponding for the other wire, so if I1=I2 they will cancel where the distance between the two is equal.]

## What produces magnetic fields within a motor?

Electric motors generate magnetic fields with electric current through a coil. The magnetic field then causes a force with a magnet that causes movement or spinning that runs the motor.

## What is the relationship between force and current?

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. Practically this means the following: If the current is doubled the force on the conductor will double.
