An electron having a charge e moves with a velocity v in X-direction. A magnetic field acts on it in Y-direction. The force on the electron acts in
A positively charged particle falls vertically downwards. The horizontal component of earths magnetic field will deflect it towards
You are sitting in a room in which a strong magnetic field is directed from your left towards right. A beam of electrons is directed from front towards you. What would be the direction of magnetic force on this beam ?
An electron is travelling along the x-direction. It encounters a magnetic field in the ydirection. Its subsequent motion will be
An electric current runs counterclockwise in a rectangular loop around the outside edge of the page which lies flat on your table. A uniform magnetic field is then turned on directed parallel to the page from the top to bottom. The magnetic force on the page will cause:
A positive charge is at rest in a uniform magnetic field directed to the right. What force does the positive charge feel, due to the magnetic field?
The direction of force on a current carrying conductor placed in a magnetic field is given by :
A vertical wire carries a current in upward direction. An electron beam sent horizontally towards the wire will be deflected (gravity free space) :
In _______ Fleming Left hand rule is not used.
Fleming's left hand rule is used to find
An electron is moving vertically downwards at any place. The direction of magnetic force acting on it due to horizontal component of earth's magnetic field will be
An electron and a proton travel with equal speeds and in the same direction, at $90^o$ to a uniform magnetic field. They experience forces which are initially
How will be the direction of force will get changed, if the current is reversed in the conductor placed in a magnetic field?
A proton is projected horizontally eastward in a uniform magnetic field, which is horizontal and southward in direction. The proton will be deflected
An electron enters a magnetic field at right angles to it. The direction of force acting on the electron will be
Which rule determines the direction of force experienced by a current Carrying straight conductor placed in a magnetic field which is perpendicular to it.
In the statement of Fleming's left hand rule, magnetic field is represented by
In the statement of Fleming's left hand rule, what do the direction of centre finger represents
In the statement of Fleming's left hand rule, force acting on the conductor is is represented by
An electron is moving towards east in a magnetic field acting vertically downwards. So the electron is deflected towards:
Fleming's left-hand rule is used to find the direction of _______ acting on the current carrying conductor placed in a/an ________ field.
At an instant a charge q moves with a velocity of 5 m/s along y-axis in a uniform magnetic filed $\underset{B}{\rightarrow}=(2\widehat{i}+3\widehat{j}+4\widehat{k})$
A charge particle is moving in the direction of a magnetic filed.The magnetic force acting on the particle:
According to Fleming's left hand rule,whose direction is indicated by thumb?
