Magnetic field lines are a visual representation of the invisible lines of force in a magnetic field. Waving a single compass around a magnetic field shows the direction of the field lines. More filings can be added to make the field lines more clear, but only up to a point.Since compasses work by pointing along magnetic field lines, this means that there must be a magnetic field near the wire through which the To help you visualise this situation, stand a pen or pencil straight up on a desk. The circles are centred around the pencil or pen and would be drawn...Magnetic field lines can be mapped out using a small compass. The compass is moved from point to point around a magnet, and at each point, a short line is drawn Bringing two north poles together—or two south poles—will cause a repulsion, and the magnetic field lines will bend away from each other.A magnetic field line can never cross another field line. The magnetic field is unique at every point in space. Magnetic field lines are continuous and unbroken, forming closed loops. The direction of magnetic field lines is defined to be the direction in which the north end of a compass needle points.A magnetic field line or magnetic flux line shows the direction of a magnet's force and the strength of a magnet. The idea of lines of force was invented by Michael Faraday. His theory is that all of reality is made up of force itself.

a compass points the magnetic north pole,because the earth is tilted on an axis of 23 degrees, while spinning on this same axis.that is why a compass points force at your locality.It picks up the earth's magnetic field.answer 2 A magnetic compass needle aligns itself with the lines of magnetic force......Direction Of The Magnetic Field (C) - With The North Pole Pointing In The Direction Of The Magnetic Field 2 - The Magnetic Field Lines Due To A Straight (C) - with the north pole pointing in the direction of the magnetic field. 2 - The magnetic field lines due to a straight, current-carrying wire...Magnetic Field Line Using Compass - Magnetic Effect of Current (Chapter 15): CBSE Class 10 Science Dear students for DronStudy Website, Please visit: https...Magnetic field lines can be mapped out using a small compass.

The lines of magnetic field from a bar magnet form closed lines. By convention, the field direction is taken to be outward from the North pole and in to the South pole of the magnet. Unlike magnetic poles attract, so the north indicator of the compass will point toward the south pole of a magnet.Detecting magnetic fields. A magnetic field is invisible, but it can be detected using a magnetic compass. When a plotting compass is placed in the Earth's magnetic field, the north pole of the compass will line up with the Earth's magnetic field lines and point to magnetic south.Now, assuming that the magnetic field from the magnet is surrounding the compass needle with such strength that we can ignore Earth's magnetic field, we will be able to explore the A magnetic compass near those locations would be extremely inaccurate as it lined up with the magnetic poles.Magnets attract other magnets (as you can see), and also attract some kinds of metal like many kinds of steel. However, the directions of those magnets are all scrambled up, so the total magnetism cancels out. If you put them in a magnetic field, the domains tend to line up with the field, so you...magnetic field due to a nearby magnet or current-carrying. field is simply the vector sum of all contributing fields Table I shows the magnetic field strength of the Earth in a. A compass works by allowing a small magnetized needle to line up with the horizontal component of the net magnetic.

Ah, definitions. c) is out. The route of a magnetic field is the route the north-pointing finish of a compass needle would point in that field. This issues towards the North Pole on earth. But opposite poes draw in and like poles repel. This means that the red-painted north-pointing finish of a compass needle is in truth a south pole. (stay that secret) And correspondingly, the other finish of the needle is a north pole (of the needle) Thus, the north pole of the needle issues opposite to the magnetic field, as a result of its other finish (secretly a south pole) is pointing north in the route fo the magnetic field.
