How can one determine the poles of the magnetised iron bar?
To determine the poles of a magnetized iron bar, you can use a compass. One end of the bar that attracts the north-seeking end of the compass needle is the north pole of the bar. The opposite end that attracts the south-seeking end of the compass needle is the south pole of the bar.
How can you make a compass needle point toward Earth's SOUTH pole?
You don't have to do anything to it.It's impossible to make a magnet that has only one magnetic pole. Any magneticobject that you happen to be using as a compass has two poles on it. Hang theobject up on a string, or mount it on a pivot. One of its poles points to Earth'snorth magnetic pole, and the other end of it points to the Earth's south magneticpole.(Note that the compass points to the Earth's magneticpoles, and has no ideawhere the geographic poles are. If you're in a situation where your safety oryour job may involve the use of your compass, then it's important to know thedifference.)
How can you use a compass to find directions on Earth?
A compass needle points to the magnetic north pole. Earth has two different sets of poles the goegraphic and the magnetic pole... hope i helped some! Love ya! Rogers (vball # and bball # 4)
What the best material to use as a compass needle?
The best material to use as a compass needle is magnetized steel. Steel is strong, magnetizable, and maintains its magnetic properties well. It is also readily available and cost-effective for compass construction.
What magnetized steel needle that aligns with the magnetic of the earth is a?
A compass needle is a magnetized steel needle that aligns with the Earth's magnetic field. Its use allows for determining directions such as north, south, east, and west.
How do you use an ordinary Compass?
To use an ordinary compass, hold it flat in your palm and make sure the needle can move freely. Rotate yourself and the compass until the needle points to the north direction marked on the compass. Now you can determine the other directions (east, west, south) based on the north reading.
How would you tell someone how to use a compass?
To use a compass, first hold it flat in your hand and make sure the needle is pointing north. Then, rotate yourself and the compass together until the red end of the needle aligns with the "N" on the dial. Your direction of travel is now indicated by the direction of the compass arrow. Remember to account for declination if necessary.
How can you tell which is the North Pole on a magnet if it is not marked?
A magnet's north pole will attract the south pole of a compass needle (i.e. the end of the needle that points to Magnetic South).
What is the function of liquid chamber in a magnetic compass?
The liquid is there to dampen the movement of the needle. Without the liquid, the needle would spin and jiggle about rapidly. Hence the need to slow the movement down - it makes the compass easier to use.
What tool would you use to detect magnetic effects?
A magnetic needle meter, or a simple compass.
Describe the effects and evidence of Earth's magnetic field?
The magnetic field can easily be noted if you hang a magnet from a piece of string, or use a compass; the compass needle is also magnetic. The idea is for the compass or hanging magnet to be able to freely rotate. Since the north pole of the compass needles points north, you can conclude that the south pole of planet Earth is towards the north. Remember that opposite poles attract each other.
How do you use a compass to find the flow through a wire?
A compass can be used to find the flow of current through a wire by placing the compass near the wire. The needle of the compass will align with the magnetic field created by the current flowing through the wire, indicating the direction of the current flow. The needle will point in the direction from which the current is coming.
