What Can Magnets Be Used For? Magnets are used to make a tight seal on the doors to refrigerators and freezers. They power speakers in stereos, earphones, and televisions. Magnets are used to store data in computers, and are important in scanning machines called MRIs (magnetic resonance imagers), which doctors use to look inside people’s
When The Switch Is Pressed What Will Happen To Electromagnet? Magnetic field lines These show the shape of a magnetic field. You can show magnetic field lines with iron filings. Electric bell: When you push the switch, the current flows in the coil of wire, the electromagnet turns on and attracts the iron armature. Does
Why Can’t Two Field Lines Intersect Each Other? The magnetic field lines never intersect each other because if two or more lines intersect each other than it means that at that point of intersection, the magnetic field has two directions at the same point. This is not possible for a magnetic field to point in
Does Time Dependent Magnetic Field Generates Electric Field? Asseration: Time dependent magnetic field generates electric field. Reason: Direction of electric field generated from time variable magnetic field does not obey Lenz’s law. Does a changing magnetic field produce an electric field? The third is a statement of Faraday’s law of magnetic induction, which reveals that
Which Best Describes The Electromagnetic Force? Electromagnetic force is the force which causes electric and magnetic effect such as repulsion between like charges or between two like poles of a magnet. This forces is long ranged and stronger with infinite range. It can be attractive or repulsive. What describes the electromagnetic force? The electromagnetic force,
Why Do The Iron Filings Arrange In A Pattern? The iron fillings arrange themselves in a pattern because they get attracted by the bar magnet. The pattern that they form can also be called the magnetic field lines of the bar magnet. Why do the iron filings arrange in such a pattern B What does
Does Wrapping More Wire Around A Nail Make An Electromagnet Stronger? Neatly wrap the wire around the nail. The more wire you wrap around the nail, the stronger your electromagnet will be. Make certain that you leave enough of the wire unwound so that you can attach the battery. How can you increase the strength
What Is The Value Of Magnetic Field At A Point On A Straight Thin Current Carrying Wire Give Too? Hence the magnetic field induction at any point on the conductor itself is zero. What is Biot-Savart law calculate the magnetic field at a point due to a straight current wire? The magnetic field at point
What Happens To The Speed Of A Charged Particle In A Magnetic Field? Since the magnetic force is perpendicular to the direction of travel, a charged particle follows a curved path in a magnetic field. … The magnetic force is perpendicular to the velocity, so velocity changes in direction but not magnitude. The result is
How Do You Find The Electric Field In A Vacuum? Your field can then be described as E=Ez(x,y,z)ˆz. As an electrostatic field, this must satisfy Gauss’s law, which in vacuum reads ∇⋅E=∂Ez∂z=0, and means Ez cannot depend on the z coordinate. More intuitively, the electric field cannot change its magnitude along its direction in the
