Whether axis of magnetic dipole antenna should be aligned with the magnetic field of the wave to get better reception as in electric dipole antenna.
![Check Mark](/static/check-mark.png)
Answer to Problem 1CQ
Yes, the magnetic dipole antenna should be aligned with the magnetic field of the wave to get better reception. The plane of antenna should be perpendicular to magnetic field to maximize the rate of change of flux.
Explanation of Solution
In electric dipole antenna, better signal reception will take place if it is aligned with electric field of the wave. If the wave is not parallel to antenna, only component of electric field that is parallel to the antenna contribute to oscillating current. In such case, current and emf will be reduced by factor of
In similar way axis of the loop of the antenna should be aligned with magnetic field of the wave. Induced emf produced in antenna makes an alternating current flow in antenna. The induced emf is produced by the changing magnetic flux associated with antenna due to oscillating magnetic field of the wave. To get maximum rate of change of flux, the plane of antenna should be perpendicular to magnetic field. Therefore, to induce maximum current in antenna, axis of loop should be aligned with magnetic field.

(a) Describe the directions (angle 1) at which the small object can emerge after colliding elastically with the cube. How does 1 depend on b, the so-called impact parameter? Ignore any effects that might be due to rotation after the collision, and assume that the cube is much more massive than the small object. (b) Answer the same questions if the small object instead collides with a massive sphere.arrow_forward2. A projectile is shot from a launcher at an angle 0,, with an initial velocity magnitude vo, from a point even with a tabletop. The projectile hits an apple atop a child's noggin (see Figure 1). The apple is a height y above the tabletop, and a horizontal distance x from the launcher. Set this up as a formal problem, and solve for x. That is, determine an expression for x in terms of only v₁, 0, y and g. Actually, this is quite a long expression. So, if you want, you can determine an expression for x in terms of v., 0., and time t, and determine another expression for timet (in terms of v., 0.,y and g) that you will solve and then substitute the value of t into the expression for x. Your final equation(s) will be called Equation 3 (and Equation 4).arrow_forward
