# You asked: What is electromagnetic force Class 11?

Contents

Electromagnetic Force: It is the force between charged particles. Charges at rest have electric attraction (between unlike charges) and repulsion (between like charges). Charges in motion produce magnetic force. Together they are called Electromagnetic Force.

## What is an electromagnetic force field?

An electromagnetic field (also EM field) is a classical (i.e. non-quantum) field produced by moving electric charges. … The way in which charges and currents interact with the electromagnetic field is described by Maxwell’s equations and the Lorentz force law.

## What is an electromagnet short answer?

An electromagnet is a magnet that runs on electricity. Unlike a permanent magnet, the strength of an electromagnet can easily be changed by changing the amount of electric current that flows through it. The poles of an electromagnet can even be reversed by reversing the flow of electricity.

## What best describes the electromagnetic force?

Electromagnetic force is the force which causes electric and magnetic effect such as repulsion between like charges or between two like poles of a magnet. This forces is long ranged and stronger with infinite range. It can be attractive or repulsive.

## What is Force class 11th?

In Physics, force is defined as: The push or pull on an object with mass that causes it to change its velocity. Force is an external agent capable of changing the state of rest or motion of a particular body. It has a magnitude and a direction.

## Which force is the strongest force?

The strong nuclear force, also called the strong nuclear interaction, is the strongest of the four fundamental forces of nature. It’s 6 thousand trillion trillion trillion (that’s 39 zeroes after 6!) times stronger than the force of gravity, according to the HyperPhysics website.

## What are the 4 fundamental forces?

Fundamental force, also called fundamental interaction, in physics, any of the four basic forces—gravitational, electromagnetic, strong, and weak—that govern how objects or particles interact and how certain particles decay.

## What is meant by electro magnet?

: a core of magnetic material (such as iron) surrounded by a coil of wire through which an electric current is passed to magnetize the core.

## What are the types of electromagnets?

There are three basic types of electromagnets: the robust ones, the superconductors and finally the hybrids. Resistant: A resistive magnet produces a magnetic field with copper wires, this executes electricity through the wire and electrons produce a weak magnetic field.

## What is electromagnet made of?

A coil with an iron core is called an electromagnet. The iron core increases the coil’s magnetic field strength. A simple electromagnet is made by coiling wire around an iron nail.

## Which best describes the weak nuclear force?

Answer Expert Verified. Weak nuclear force is weaker than the strong nuclear force with a smaller range than the. It acts between fermions with spin 1/2 basically quarks and leptons. It has a range of 10⁻¹⁸ meters.

## Which best describes Yanni’s error?

Thus, we can conclude that the statement which best describes Yanni’s error is that the strong force is responsible for radioactive decay. So it’s the strong force that overcomes repulsion and keeps the nucleus together.

## What is the force in science?

A force is a push or pull upon an object resulting from the object’s interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects.

## What are the 10 types of forces?

Action-at-a-Distance Forces

• Applied Force.
• Gravitational Force.
• Normal Force.
• Frictional Force.
• Air Resistance Force.
• Tension Force.
• Spring Force.

## What is weight class 11?

Weight is defined as the force exerted by the gravity on an object. The mass of a substance is constant whereas its weight may vary from one place to another due to change in gravity. … The SI unit of mass is kilogram.
