Alignment of a Freely Suspended Magnet
Define the magnetic field of a bar magnet.
The region around a magnet in which its force can be detected
The direction in which the magnets align themselves when suspended in air is :
Define the following items -
(i) Magnetic force (ii) Magnetic field (iii) magnetic poles
The space surrounding a magnet within which the effect of magnet is present is called ________________.
Current carrying conductor has a magnetic effect around it.
Matt has a magnetic compass which is pointing in the north-south direction. He brings a large magnet close to it. In which direction would the magnetic needle align?
It would align in the south-north direction .
It would align in the east-west direction.
It would remain unchanged.
It would align itself according to the resulting magnetic field of the Earth and the larger magnet.
In which direction does a freely suspended magnet align? [1 MARK]
The direction of magnetic field lines of a freely suspended magnet is
North to south externally
North to south internally
South to north internally
South to north externally
Magnets align themselves according to the strongest magnet around them.
Explain why ‘magnetic field lines never intersect with each other.
There is a bar in my hand. When I suspend it using a thread, it aligns itself such that one end faces the geographic North direction. It also attracts iron items. What can this bar be considered similar to?
An electric bulb
A water tank
A bar magnet
A compass has a small balanced pointer that always points North-South when suspended freely. This is because :
The Earth doesn't have any magnetic field.
The compass needle points to cold places.
Of gravitational force of the Earth.
The Earth has a magnetic field and the pointer is magnetic.
Magnetic field is a region that spreads:
for a finite region around the magnet
across a country
across the earth
- South pole
- North pole
- Field line
A magnet in the form of a cube is placed on a piece of cork that floats on water. The cube is marked with four faces W, X, Y and Z and the compass needle points in the direction as shown in the figure. The arrow beside the N symbol represents the direction of the geographical north pole.
Which of the following faces denote the N - pole and S - pole of the magnet?
N - pole (W)
S - pole (X)
N - pole (X)
S - pole (Y)
N - pole (Y)
S - pole (Z)
N - pole (Z)
S - pole (W)
