When the force on a current carrying wire is maximum?
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.
Who discovered the magnetic field of Earth?
Also in this century, Georg Hartmann and Robert Norman independently discovered magnetic inclination, the angle between the magnetic field and the horizontal. Then in 1600 William Gilbert published De Magnete, in which he concluded that the earth behaved as a giant magnet.
What is the least magnetic stainless steel?
Magnetic and non-Magnetic Stainless Steel However, the most common stainless steels are ‘austenitic’ – these have a higher chromium content and nickel is also added. It is the nickel which modifies the physical structure of the steel and makes it theoretically non-magnetic. 304 stainless steel contains chromium (min.
What is the direction of magnetic field at a point due to a magnet?
Magnetic field lines are defined to have the direction that a small compass points when placed at a location. (a) If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the north pole of the magnet, toward the south pole of the magnet.
What is magnetic field how can the direction?
The direction of magnetic field at a place can be determined by using a compass needle. A compass needle need place near a magnet gets deflected due to the magnetic force exerted by the magnet. The north an the needle of the compass indicates the direction of magnetic field at the point where it is placed.
Why does a freely suspended magnet always point north south direction?
A freely suspended magnet always rests in the north-south direction because the magnetic south pole of the earth lies in the geographic north direction and the magnetic north pole of the earth lies in the geographical south direction.
