A magnetic field can be created by running electricity through a wire. All magnetic fields are created by moving charged particles. Even the magnet on your fridge is magnetic because it contains electrons that are constantly moving around inside. The first indication that moving electric charges ca...
The magnetic field exists in the region surrounding a bar magnet and is characterized by its strength and direction.
a nearby compass would change direction. This observation led to the conclusion that the electrons moving through the wire were creating a magnetic field that didn't exist when the current was turned off. An important thing to note is that charged particles create magnetic fields only when they...
Thus a dip at the field line summit is needed before a prominence can form. We investigate different ways of forming such an upward curvature. Results with a twisted flux tube or a sheared arcade are reviewed, and a third possibility, namely a quadrupolar region is proposed....
How to Create a Magnetic Field Step 1 Wrap the wire slowly and firmly around the iron bar. This is a lot of wire and it will take some time. Wrap the wire tightly and be sure to wrap the wire only in one direction. The direction of the wrap dictates the direction of the magnetic ...
How is the direction of a magnetic field at a point determined? Mention two important properties of magnetic field lines. View Solution What are magnetic field lines? How is the direction of a magnetic field at a point determined ? Mention two important properties of magnetic field lines. ...
How does Earth's magnetic field protect us? How to make a magnetic field stronger. How is the magnetic field oriented around a magnet? How do you increase the magnetic field of a magnet? How to create a static magnetic field. What is an induced magnetic field?
I want to model this thing in COMSOL that i want to apply a certain magnetic field and see how the shape of the sphere is deformed and by how much ? Does any one has any idea that how can i do that. I have attached a picture of the my model the middle ...
The most common method of making magnets today involves placing metal in a magnetic field. CRStocker/Shutterstock To make a permanent magnet, all you have to do is encourage the magnetic domains in a piece of metal to point in the same direction. That's what happens when you rub a needl...
How does a magnetic field sensor work?I_Magnetic field sensors_:Magnetic field sensors are devices that usually detect changes in various proprties of magnetic field, such as intensity, direction and polarity.Answer and Explanation: Generally speaking, magnetic sensors can be categorized into two ...
