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.
Which particle is affected by a magnetic field?
A magnetic field (only one pole is shown) affects radioactive rays differently depending on the type of ray. Alpha rays (heavy, positively charged particles) are deflected slightly in one direction. Beta rays (light, negatively charged electrons ) are deflected strongly in the opposite direction.
Which particle is not affected by electric and magnetic field?
Gamma ray is electromagnetic wave which is neutral. So gamma ray is not affected by electric and magnetic field.
How magnetic field is created?
Conversely, a magnetic field is produced by an electric charge in motion . This is in accordance with Faraday’s Law of Induction, which is the basis for electromagnets, electric motors and generators. A charge moving in a straight line, as through a straight wire, generates a magnetic field that spirals around the wire.
Why can’t magnetic field lines cross?
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 more than one direction at the same point.
Are deflected by magnetic field?
That rule describes how a charged particle (our electron) moving in a magnetic field will be deflected by that field at a right angle to both the field and to the direction of the particle. ... The electrons in the cathode rays would deflect toward the positively charged plates, and away from the negatively charged plates.
Which particle is deflected the most in a magnetic field?
The deflection is also inversely proportional to its mass. So given a proton and an electron going at the same velocity in a magnetic field and having equal (but opposite) electric charge the electron will deflect much more since the ratio of the masses is 1836.
Are protons affected by magnetic fields?
Protons and neutrons have almost equal masses, but electrons have less mass. ... A negatively–charged electron is affected by the magnetic field. It travels into the box but its path is curved to the left. The positively–charged proton is also affected by the magnetic field and its path curves to the right.
Are photons affected by electric field?
According to photon, they can not be affected by electric and magnetic fields.
Why light is not affected by magnetic field?
The short answer is that only charged particles like electrons or protons are bent when travelling through magnetic fields . Electromagnetic radiation is made up of uncharged photons, so is unaffected.
Can a photon be deflected by an electric field?
Answer : Photon is a charge-less particle and hence it is deflected neither by an electric field nor by a magnetic field.
Can you see a magnetic field?
Magnetic fields are everywhere– you just can’t see them* . ... Usually, that’s earth’s (relatively weak) magnetic field. But they also can be used to probe the field structure around stronger magnets, as they align to the sum total field at any given location. Compasses are easy to make.
What is H in magnetic field?
The definition of H is H = B/μ − M , where B is the magnetic flux density, a measure of the actual magnetic field within a material considered as a concentration of magnetic field lines, or flux, per unit cross-sectional area; μ is the magnetic permeability; and M is the magnetization. ...
Does Earth have a magnetic field?
In a sense, yes . The Earth is composed of layers having different chemical compositions and different physical properties. The crust of the Earth has some permanent magnetization, and the Earth’s core generates its own magnetic field, sustaining the main part of the field we measure at the surface.
Can magnetic fields cross?
Magnetic field lines can never cross , meaning that the field is unique at any point in space. Magnetic field lines are continuous, forming closed loops without beginning or end. They go from the north pole to the south pole.
