the lines of force surrounding a permanent magnet or a moving charged particle.
- Pigeons navigate less accurately when the earth’s magnetic field is disturbed.
- The secondary current sets up a magnetic field inside the tube.
- The earth’s magnetic field is constantly changing in both direction and intensity.
Keeping this in view, does Earth have a magnetic field?
In a sense, yes. The Earth is composed of layers having different chemical compositions and different physical properties. The crust of the Earth has some permanent magnetization, and the Earth’s core generates its own magnetic field, sustaining the main part of the field we measure at the surface.
Correspondingly, how do you use electric field in a sentence?
1 The interaction is strong, as it involves the electric field of the radiation and the electric charge of the electron. 2 The emergence of the concept of electric field provides a particularly striking, if somewhat technical, example. 3 When subjected to an electric field, ceruloplasmin migrates as an alpha2-globulin.
What are three examples of magnetic fields?

What does a magnetic field do?
Not only does a magnetic field set the direction of our compass needles, it also acts as a shield of sorts, deflecting away solar wind that might otherwise eat away at the atmosphere. Scientists know that today the Earth’s magnetic field is powered by the solidification of the planet’s liquid iron core.
What is magnetic field and how it works?
The magnetic field is the area around a magnet that has magnetic force. All magnets have north and south poles. … When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.
What is magnetic field in simple words?
The magnetic field is the area around a magnet in which there is magnetic force. Moving electric charges can make magnetic fields. … In physics, the magnetic field is a field that passes through space and which makes a magnetic force move electric charges and magnetic dipoles.
What is magnetic field lines Class 10th?
A magnetic field is represented by a series of lines around a magnet. The path along which north pole moves in a magnetic field is called magnetic lines of force or magnetic field line. … The direction of magnetic field is taken to be the direction in which a north pole of compass needle move inside it.
What is magnetism class 6th?
A magnet is an object which attracts things made of iron, steel, nickel and cobalt. Magnets are made of iron, steel or other alloys of iron by the process of magnetisation. Magnets are made in different shapes and sizes so that they can be used for different purposes.
What is magnetism in a sentence?
attraction for iron; associated with electric currents as well as magnets; characterized by fields of force 2. the branch of science that studies magnetism. … 4) His success showed his magnetism of courage and devotion. 5) His personal magnetism drew people to the church.
What is one example of magnets in everyday life?
Magnets are used to make a tight seal on the doors to refrigerators and freezers. They power speakers in stereos, earphones, and televisions. Magnets are used to store data in computers, and are important in scanning machines called MRIs (magnetic resonance imagers), which doctors use to look inside people’s bodies.
