Answer : Perpendicular to both the magnetic field and the current direction
Explanation :
If a current-carrying wire is in a magnetic field, the magnetic force exerted on the wire is given by :
.............(1)
Where
q is the electric charge
v is the velocity with which the particle is moving
B is the magnetic field
The direction of magnetic force is can be find by using right hand rule.
From equation (1), it is clear that the direction of force exerted on the wire is perpendicular to both the magnetic field and the direction of current.
At the eutectic composition, an alloy can solidify at a constant temperature : TRUE . this is because at eutectic composition the type of reaction that takes place there is invariant reaction in its thermal equilibrium
For effective dispersion strengthening, the dispersed phase should be needle-like, as opposed to round : FALSE. because the rounded shape will not cause a crack.
Intermetallic compounds are usually hard and brittle : TRUE. because Intermetallic compounds prevents dislocation movements and this makes them brittle and hard
For the effective dispersion and strengthening, the dispersed phase should be continuous : FALSE. this is because the dispersed precipitate must be small and not continuous
Stoichiometric intermetallic compounds exist over a range of compositions : FALSE
Faster solidification results in smaller interlamellar spacing : TRUE
