What are two fields surround a moving electric charge?
A moving electric charge will produce a magnetic field.A moving electric charge will produce a magnetic field.A moving electric charge will produce a magnetic field.A moving electric charge will produce a magnetic field.
How do you know that a force is negative or positive in relation to magnetic field?
It depends on what direction is considered positive and what direction is considered negative. For this case, I'll assume that up, right, and outward are positive and down, left, and inward are negative. Since the force is perpendicular to the magnetic field, the sign for the force depends on the direction of the current. If the current is inward and the magnetic field is to the left, then the force is upward and thus positive. If the current would be outward and the magnetic field would be still to the left, then the force is downward and thus is negative. The best way to think of this is to use the "right-hand" rule. Use your index finger to represent the direction of the current, your thumb as the direction of the force, and the other three fingers as the direction of the magnetic field direction.
Why force exerted by a magnetic field on stationary elctric dipole is zero?
The force on a charge by a magnetic field is given by F = Bq v sin@ v - the speed of the charged particle with charge q. B - magnetic field induction in tesla. @ is the angle between the velocity vector and magnetic field vector. As dipole is stationary, the speed of charges is zero. So the force = 0 Hence the result.
What happens to the magnetic field of a wire when you change the direction of the current of the wire?
If iron piece is place in its field, the direction of the magnetic lines of force change towards North and South as in the case of a magnet. North represents North Pole and South for South Pole.
How are magnet fields and electric fields alike?
Both act only on charged particles (ions, protons, or electrons). ?However, an electric field (which generates an ELECTRIC FORCE) acts on a particle in the same direction as the field, given by the equation:F(vector) = q*E(vector)The resulting force vector is in the same direction as the field vector (for positive charges).A magnetic field generates a force ONLY on a MOVING charge, and ONLY if the charge is moving non-parallel to the magnetic field:F(vector) = q*v(vector) x B(vector)Because of the cross-product, the magnetic force is a direction perpendicular to the velocity and magnetic field vectors (use the right hand rule to figure out the direction of magnetic force). ?The particle will still have momentum from its initial velocity, so an applied magnetic field will (pretty much) always make the particle move in a curved path.
Does a magnetic field exert any pressure on a charge moving perpendicular to its direction?
Only moving charges experience force in a magnetic field. i.e.,on moving ,a charge q,with velocity v ,experiences a force in the presence of electric field(E) and magnetic field (B). It can be represented as F= q(v x B)~(Ftotal=Felectricfield + Fmagneticfield ) Force acts perpendicular to both magnetic field and velocity of the electron. Its direction is given by right hand thumb rule or screw rule. The magnetic force is zero if charge is not moving, since lvl=0.
When a charge move in the same direction as the magnetic field lines the magnetic force is?
The magnetic force is F=qV.B = -qvB cos(VB).
What is the effect of a magnetic field on a stationary electric field?
The magnetic field will have no effect on a stationary electric charge. ( this means that the magnetic field is also stationary. ) If the charge is moving , relative to the magnetic field then there might be an effect, but the size and direction of the effect will depend on the direction of the electric charge as it moves through the field. If the charge is moving parallel to the field there will be no effect on it. If the charge is moving at right angles to the field then it will experience a force that is mutually orthogonal to the field and direction of the motion. You really need diagrams to properly explain this
What is a magnetic field vector?
It is a way of representing the magnetic force at a point in the field. The magnitude and direction of the vector represents the strength and the direction of the magnetic force acting on a charged particle in the field.
The force on an electron moving in a magnetic field will be the largest when its direction is?
perpendicular to the magnetic field direction
Does a magnetic field attract electricity?
When the electrical charge is stationary in a magnetic field then no force would act on the charge. But if the charge is in motion that too in an inclined direction with the magetic field then a force would act on the moving charge. This force is named as Lorentz magnetic force
What are two fields surround a moving electric charge?
A moving electric charge will produce a magnetic field.A moving electric charge will produce a magnetic field.A moving electric charge will produce a magnetic field.A moving electric charge will produce a magnetic field.
Is the direction of the electric force on a charge is tangent to the field line?
yes,the direction of electric force on a charge is tangent of field lines.
How are electric force and magnetic force similar?
Both act only on charged particles (ions, protons, or electrons). ?However, an electric field (which generates an ELECTRIC FORCE) acts on a particle in the same direction as the field, given by the equation:F(vector) = q*E(vector)The resulting force vector is in the same direction as the field vector (for positive charges).A magnetic field generates a force ONLY on a MOVING charge, and ONLY if the charge is moving non-parallel to the magnetic field:F(vector) = q*v(vector) x B(vector)Because of the cross-product, the magnetic force is a direction perpendicular to the velocity and magnetic field vectors (use the right hand rule to figure out the direction of magnetic force). ?The particle will still have momentum from its initial velocity, so an applied magnetic field will (pretty much) always make the particle move in a curved path.
What is the path of charge particle inside magnetic field when it enters a magnetic field at right angles to it?
Depending on the direction of the magnetic field and the charge on the particle, the charge would move in a circular fashion either clockwise or anticlockwise depending on the circumstance. Using the right hand palm (push) rule, find the direction of the force (palm) and the charge continues on that path in a circular motion. If the particle leaves the field, it continues in that direction traveling in a straight line unless under other influences.
Why a stationary charge do not feel any force in magnetic field?
we know that force on a charge in magnetic field F=qvbsinx q-charge v-velocity b-strenth 0f magnetic field x-angle between the motion of chage and the magnetic field as the charge is stationary so v=0 so,F=0 so charge donot fill any force on it.
Why does a moving charge experience force when it it moves in magnetic field?
It experiences a force.
