What is needle magnet?
A needle magnet is a type of small, strong magnet that is shaped like a needle. It is commonly used for picking up small metallic objects like pins, needles, or screws that are hard to reach or see. Needle magnets are also used in compasses to indicate direction.
What is a plotting compass?
A plotting compass is a small magnet which is suspended and is free to rotate. When it is near a magnet, the compass will always point in a particular direction (the north pole's direction) becasue of the force of the magnetic field.
Can small permanent magnet motors be reverse direction if the direction of current flow to the motor is reverse?
Permanent magnet field motors. With a these motors, a permanent magnet is used to replace the field coil. DC power is connected via the brushes, to the armature only. Reversing the polarity, will cause the motor to reverse its direction of rotation. It is very common to use a switch to intentionally reverse to the polarity, to allow reversal of the motor if desired.
How a compass can be used to trace the magnetic field of the magnet?
A compass can be used to trace the magnetic field of a magnet by placing the compass near the magnet. The needle of the compass will align with the magnetic field lines, allowing you to visualize the direction of the field. By moving the compass around the magnet, you can map out the shape and direction of the magnetic field.
What is the bat gimmick?
A small magnet used for PK effects.
Can a magnet be used for finding direction?
Yes. That is exactly what a magnetic compass does.a magnet, as in a fridge magnet cannot, but a magnetic compass can. a magnet compass points and directs itself the the north pole, where magnetic fields are located; this is why a magnetic compass can find directs as in NORTH SOUTH EAST OR WEST, it cannot say find it's way from say second street to third street,
What was a swinging magnet used for?
A swinging magnet was often used in old-fashioned compasses to indicate direction based on Earth's magnetic field. The magnet would align itself with the Earth's magnetic field, pointing towards the magnetic North Pole.
What is a thin flat circular magnet?
A thin flat circular magnet is a magnet that is disk-shaped with a small thickness. It is commonly used in applications where a strong magnetic field is needed in a compact form, such as in sensors, magnetic switches, or small electric motors.
A small magnet that can trun freely is a?
A small magnet that can turn freely is called a compass. Compasses align with the Earth's magnetic field and can be used to find directions such as north, south, east, and west.
How can clouds be used in navigation?
they can give you the direction of the wind... and if you know the direction of the wind you can use this to find what direction your travelling in!
What is the mass of a magnet?
The mass of a magnet can vary depending on its size and composition. A typical small refrigerator magnet may have a mass of a few grams, while larger magnets used in industrial applications can weigh several kilograms.
Do iron filings create waves when attracted by a magnet?
Magnetic waves are used to move the iron but the iron does not give off magnetic waves until it is touching the magnet
