When it comes to magnets, opposites attract. This fact means that the north end of a magnet in a compass is attracted to the south magnetic pole, which lies close to the geographic north pole. Magnetic field lines outside of a permanent magnet always run from the north magnetic pole to the south magnetic pole.
Why does a bar magnet always align in the north south direction when freely suspended?
Accepted Answer: The earth behaves as a magnetic dipole . Therefore a freely suspended magnet always points towards in the north-south direction because the north pole of the suspended magnet attracts the south pole of the earth’s magnet which is the geographical north pole of the earth.
In which direction does the magnet stop every time?
One end of any bar magnet will always want to point north if it is freely suspended. This is called the north-seeking pole of the magnet, or simply the north pole. The opposite end is called the south pole.
Does the bar magnet stop in the same direction each time?
If a bar magnet is suspended so that it rotates freely, one pole of the magnet will always turn toward the north, with the opposite pole facing south. … It was then noticed that the north poles of two different magnets repel each other, and likewise for the south poles.
What will happen when the direction of current in the solenoid is reversed?
The direction of magnetic field is always perpendicular to the direction of current flow and the magnitude of the magnetic field inside a solenoid is directly proportional to the current flowing through the solenoid. Thus,when the current through the solenoid is reversed,the direction of magnetic field is reversed.
What is the direction of freely suspended magnet how we can observe the direction of magnet?
freely suspended magnet always points in the North-South direction even in the absence of any other magnet. This suggests that the Earth itself behaves as a magnet which causes a freely suspended magnet (or magnetic needle) to point always in a particular direction: North and South.
Are 2 magnets stronger than 1?
Two magnets together will be slightly less than twice as strong as one magnet. When magnets are stuck entirely together (the south pole of one magnet is connected to the north pole of the other magnet) you can add the magnetic fields together.
How we can observe the direction of magnet?
A compass is an instrument which is used to find the direction of a magnetic field. A compass consists of a small metal needle which is magnetised itself and which is free to turn in any direction. Therefore, when in the presence of a magnetic field, the needle is able to line up in the same direction as the field.
What happens when two magnets are placed side by side?
When the two magnets are close to one another, we saw more pull force when the poles are facing in opposite directions. We find less pull force if the poles are facing in the same direction. When the two magnets are far enough apart, the magnetization direction doesn’t seem to matter very much.
What is the direction of magnetic field inside a bar magnet?
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.
Why do the iron filings near the bar magnet seem to align in the shape of closed curves?
Answer. Answer: Iron fillings arrange themselves in closed loops around a bar magnet because magnetic field lines influences it which is closed curved…. Hence iron fillings arrange themselves in closed loops around a bar magnet…
What will happen if a magnet is brought near a compass class 6?
When another magnet is brought near a compass, then this magnet will attract or repel the magnetic needle of compass due to which the compass needle will be disturbed from its usual north-south direction. The compass needle will point in another direction.
Can a freely suspended solenoid?
No, current carrying solenoid fall freely stay in North – South direction because it behaves as a bar magnet. When current flow through a solenoid is reversed the it direction is also reversed.
What is the direction of current in a solenoid?
Wrap the fingers of your right hand around the solenoid in the direction the current is flowing. The thumb of your right hand will show you the direction of the magnetic field through the form, pointing toward the end where the North magnetic pole will be.
What happens to the heating effect when the direction of current is reversed?
Answer. But heating is independent of the direction of current so there will be no effect on heating if direction of current is reversed.5 мая 2020 г.
