How Does The Magnetic Field Due To A Long Straight Wire Carrying Current Vary With Distance From The Wire R? The magnetic field from a wire decreases with distance from the wire. Instead of the field being proportional to the inverse square of the distance, as is the electric field from a point charge, the
Do Magnetic Field Exist Without Electric Field? They may also exist independently. Without the electric field, the magnetic field exists in permanent magnets and also with current carrying conductor and without magnetic field, electric field exists in charges at rest. So, both the electric and magnetic fields exist without each other. How can you make
Where Is The Magnetic Field The Strongest And Why? The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole when compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the
Can A Human Be Magnetic? Today, two hundred years later, we know that the human body is indeed magnetic in the sense that the body is a source of magnetic fields, but this body magnetism is very different from that imagined by Mesmer. Are magnets good for the human body? Although they have been used
Why A Stationary Charge Does Not Experience Any Force In Magnetic Field? It is because magnetic force acts on moving charges . Since the charge is stationary , no magnetic force will act on it. in order for the charge to experience magnetic force it’s magnetic field should keep on changing while intersecting other one.
Which Of The Following Statement Is Correct About The Magnetic Field Lines? Magnetic field lines make closed rings for single magnetic poles that don’t exist, unlike an electric charge. Therefore, these lines always form closed loops and option(B) is correct. Note: Magnetic field lines are imaginary lines that describe magnetic fields. It provides the path
Which Particle Will Be Deflected The Most? The greater the charge and smaller the mass, the greater the extent of deflection. The charge of both an electron and proton have the same magnitude of 1 unit. Since electrons have a much smaller mass as compared to protons, electrons will be deflected more. Which particle is
Why Does The Kinetic Energy Of A Charged Particle Moving In A Magnetic Field Remains Constant? Since the magnetic force is perpendicular to the direction of travel, a charged particle follows a curved path in a magnetic field. … The particle’s kinetic energy and speed thus remain constant. The direction of motion is affected but
How Strong Is The Human Electromagnetic Field? Through these sources, the average person is exposed to magnetic fields reaching 0.1 microtesla in strength on a daily basis. By comparison, the Earth’s magnetic field, which we are always exposed to (as long as we remain on the planet’s surface), is about 500 times stronger. Do our
Which Particle Is Not Affected By A Magnetic Field? Because they consist of charged particles, alpha and beta radiation Which is not affected by magnetic field? Explanation: A stationary charge is not affected by a magnetic field because stationary charges do not have any velocity. Magnetic field cannot occur in a particle having zero velocity.
