# How do you find the magnetic force of a wire?

## 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 magnetic force on the wire?**

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.

### How are the force on the wire and the force on the magnet related?

The magnetic force on a current-carrying wire is perpendicular to both the wire and the magnetic field with direction given by the right hand rule.

**What causes a magnetic force in a wire?**

When a wire is moved in a magnetic field, the field induces a current in the wire. Conversely, a magnetic field is produced by an electric charge in motion. A charge moving in a straight line, as through a straight wire, generates a magnetic field that spirals around the wire.

## 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.

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

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. The body does not accumulate any current.

### What is magnetic force Class 6?

Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron.

**What is the formula of magnetic field?**

The magnitude of the force on a wire carrying current I with length L in a magnetic field is given by the equation. F=ILBsinθ where θ is the angle between the wire and the magnetic field. The force is perpendicular to the field and the current.

## Why unit of magnetic field is tesla?

The tesla (symbol T) is the derived SI unit of magnetic flux density, which represents the strength of a magnetic field. One tesla represents one weber per square meter. The equivalent, and superseded, cgs unit is the gauss (G); one tesla equals exactly 10,000 gauss.

**How is the force of magnetism on a wire determined?**

It is possible to determine the force of magnetism exerted on a current-carrying wire passing through a magnetic field at right angles to the wire. Experiments show that the magnitude of the force, , on the wire, is proportional to the strength of the field, , the current, , in the wire, and the length, , of the wire in the magnetic field.

### How are magnetic forces used in an experiment?

In this experiment, you will investigate the magnetic force between two current carrying wires. One wire will be a coil of 10 turns and the other will be a coil of 38 turns. The 10-turn coil will be taped to one end of a pivoted balance beam. The beam pivots on two pins.

**How to predict the nature of the magnetic force?**

1. To predict and verify the nature of the magnetic force acting on a current-carrying wire when the wire is placed in a magnetic field. INTRODUCTION G The force on a segment ds G of a wire carrying current Iin a magnetic field B ext is given by G G G d F =Id s ×Bex t (6.1) G where B

## How does a wire loop create a magnetic force?

This wire loop is then placed into the permanent magnet assembly so the wire loop is perpendicular to the magnetic field but is not touching the magnets. Then, when a current flows through the wire loop, a magnetic force is created.
