What happens to electrons in an iron object when the object is magnetized?
When an iron object is magnetized, the electrons in the iron align their magnetic moments in the same direction, creating a magnetic field within the object. This alignment of magnetic moments enhances the overall magnetic properties of the iron object, making it magnetic as well.
What is an anemoeter?
An anemometer is a device used to measure the speed of wind. It typically consists of a set of cups that spin in the wind, and the speed of rotation is used to calculate the wind speed. It is commonly used in weather stations and on aircraft.
What is an anomometer?
An anemometer is a device used to measure the speed of the wind. It typically consists of small cups that spin in the wind, with the rotation speed being proportional to the wind speed. This device is commonly used in weather stations and for wind energy applications.
What is the most important cause of magnetism in materials A.molecular movement B.atomic spin C.elemental bounce D.electron spin?
D. electron spin. Magnetism in materials is primarily caused by the alignment and spin of electrons in the atoms. When electrons have aligned spins, they create a magnetic field, resulting in magnetism in the material.
What direction does a typhoon spin?
In the Northern Hemisphere, typhoons spin counterclockwise. In the Southern Hemisphere, they spin clockwise. This is due to the Coriolis effect, which is caused by the Earth's rotation.
What is a device that has a magnetized needle that spin freely?
A compass has a magnetized needle that can spin freely.
Does water pump pulley move on 1999 chrysler cirrus?
It should spin freely, but not wobble.It should spin freely, but not wobble.
What has to occur for an electric motor to spin freely?
In order for an electric motor to spin freely you will have to make sure you have one thing. You have to have the electric current for the motor to run freely.
How do you spin a thread?
Use a needle punk.
Why does a bicycle spin more freely if it is oiled freely?
because oil reduces friction
Should a car heater fan spin freely?
yes
What are bearings for on a skateboard?
Bearings are used to let the wheels spin freely and with minimal drag.
What is the needle in a homemade compass made out of?
Any magnetized object that can be floated on water or oil with very little friction will work. The ones that work best are things like magnetized straight-pins and sewing needles. I have a home-made compass in my office. I cut the straight part out of the bottom of a metal coat-hanger, magnetized it, and hung it balanced from a piece of thread taped to the ceiling. For relaxation that only an Engineer could appreciate, I like to give it a gentle spin on the end of the thread, then sit back, and watch it oscillate back and forth and finally come to rest pointing north again. In this way, I can kill an hour whenever I want to.
What joint allows connected shafts to spin freely while permitting a change in direction?
universal joint
Should wheel spin freely on front of vehicle when jacked up?
Yes.. with a litt resistance

Why does the record have to be spinning to produce sound?
The sound is created by a stylus (needle) physically tracing the grooves on the spinning record. As the needle moves through the grooves, it vibrates and these vibrations are converted into an electrical signal that gets amplified and then played through speakers as sound. Without the spinning motion, the needle wouldn't have anything to trace and there would be no sound generated.
