Why do we apply magnetic field only in z direction?
Applying a magnetic field only in the z-direction simplifies the analysis of a system, making calculations more straightforward. Additionally, it allows researchers to isolate the effects of the magnetic field in one direction, making it easier to control and manipulate the interactions between the field and the system under study.
What is the significance of the z component of the magnetic field outside the solenoid in relation to its overall magnetic field characteristics?
The z component of the magnetic field outside a solenoid is significant because it determines the direction and strength of the magnetic field in that region. It contributes to the overall magnetic field characteristics of the solenoid by influencing the field's orientation and intensity outside the solenoid.
What causes the magnetic field?
The magnetic field is caused by the movement of electrically charged particles, such as electrons, within a material. This movement creates a magnetic field around the particle, which can align with the magnetic fields of neighboring particles to create larger magnetic fields. Additionally, the Earth's magnetic field is generated by the movement of molten iron in its outer core.
What are magnetic substances?
Magnetic substances are substances containing aligned dipoles. Dipoles are spinning electrons. In order for something to be magnetic, its dipoles must be aligned with each other, so that they face the same direction. The direction they face create a North end, while the opposite end creates a South end.Some substances, known as ferromagnetic substances, have permanently aligned dipoles. Other substances, such as paramagnetic and dimagnetic substances, require an external magnetic field to align, or 'induce' the dipoles of the substance.To conclude, magnetic substances contain dipoles which are permanently aligned, or can be aligned through the force of external magnetic fields.Diamagnetic Substances are those Substances there is no resultant field as the magnetic field produce by both the spin and orbital motions of the electrons might add up to zero.
How are electric and magnetic fields related?
Electric and magnetic fields are by two constants, the speed of light and the free space impedance z=375 Ohms. E = cB = zH = zcD The electric charge q is related to the magnetic charge Weber phi =qz volt second. The free space impedance is related to Planck's Constant and is the ratio of the Quantum magnetic charge M and the Quantum Electric charge Q, z= M/Q. Planck's Constant h=MQ = zQ2. M = 500 e-18 Webers and Q = 4/3 e-18 Coulombs.
Why Do transverse magnetic mode has no magnetic line is in direction of propagation?
No. It has. Since transverse electric mode has it's wave propagating in the Z direction, and has magnetic field existing in the same direction with NO electric field... Likewise, transverse magnetic mode has it's wave propagating in the Z direction and has electric field existing in the same direction with NO magnetic field.

Is it true In an electromagnetic wave if the E-field is in the y-direction and the B-field is in the z-direction the wave also propagates in the z-direction?
No. The E and B vectors are perpendicular to each other, and both are perpendicularto the direction of propagation.In the situation described in the question, the wave propagates in the x-direction.(The Poynting vector ... indicating the direction of energy transfer, is E x B .)
What is the definition of a propped cantilever beam?
A beam with a built in support at one side (ie no rotation about or translation in the x, y, z direction) and a point support at the other (ie no translation in the x, y, z direction but rotation about the z direction)

Why TEM wave is not supported by hollow waveguide?
Arif Ullah khan utman kheel this is because for conductor E parallel is zero this means that the surface of the wave guide is at equipotential and this potential follow the laplace equation .it means that there is no maxima and minima inside the wave guide . this means that the electric field inside zero . hence the TEM do not exist in wave guide only TE and TM can be exist . if we place some conductor in the wave guide then the conductor inside will not be equipotential and the TEM waves can be exist . like in Coaxial cables

Why does an electric current have a magnetic field?
A current carrying conductor, such as a metal wire, will produce a magnetic field around it because of the motion of charge within the wire itself. This motion produces or sets up a magnetic field around the wire in the form of concentric circles. This electromagnetic effect is described in physics by the Biot-Savart Law, an experimentally deduced inverse-square law. The effect is also described by Ampère's Law, which is derived from the Biot-Savart Law. This law relates magnetic field and current. Also, a magnetic field that is set up by an electrical current will produce a magnetic force. This force depends on the rate of charge transfer and the magnetic field. The force produced by a current-carrying wire depends on the length, the magnetic field, and the current, which is the charge flow per unit of time.

How do you use Guass' law to derive the electric intensity due to a circular loop of charge at a point outside of the loop?
I'm going to assume that the point in question is on the z-axis and that the ring lies on the x-y plane with its center at the origin. If this assumption isn't true, then message me because the math becomes REALLY ugly.First of all, Electric intensity = Force/test charge = Electric field*test charge/test charge = Electric field.Secondly, the electric field is given by Gauss's law:∫s E•dA = Q/ε0Now, I'm going to cheat a little, so pay attention:I'm switching to spherical coordinates right off the bat.You can consider each point on the ring as a point charge. Assuming that the electric field of a point charge is spherically symmetrical, the surface integral just becomes the surface of a sphere, so Gauss's law becomes:4*PI*r2*E = Q/ε0 If that doesn't make sense, think about it a bit. So:E = Q/(k*r2)r^ where k = 4*PI*ε0 and r^ is the unit vector in the direction r.Now, we want to add up the electric fields for every point on the ring. Since our point lies on the z-axis, r is the same for every every electric field we're adding up. Therefore, we're just adding up each charge. dE = dQ/(k*r2)r^. Easy enough right? Well, the r^ term is a bit confusing since every dE is pointing in a different direction. Well, It should be obvious from symmetry that the only component of r^ that won't end up canceling are those in the z direction. Therefore, we should switch to Cartesian coordinates.the conversion equations are:r2=x2+y2+z2z=r*cosθcosθ=z/sqrt(x2+y2+z2)So, in the z direction, dEz = dE*cosθ*z^ , where z^ is the unit vector in the z direction.=dQ/(k*r2)*cosθ*z^,=dQ/(k*x2+y2+z2)*z/sqrt(x2+y2+z2)*z^,Since the radius of the loop, R, is sqrt(x2+y2), we havedEz = dQ/(k*R2+z2)*z/sqrt(R2+z2)*z^So, assuming an even charge distribution on the ring, Electric intensity is:Ez = (1/k)*(Qtot*z)/(R2+z2)3/2*z^, where Qtot is the total charge on the ring.
If a variety of singly ionized atoms travel at the same speed through the magnetic field would you expect them all to be deflected by the same amount?
No, the deflection of ions in a magnetic field depends on their mass-to-charge ratio (m/z) rather than their speed. Heavier ions with larger mass-to-charge ratios will be deflected less than lighter ions with smaller mass-to-charge ratios. Therefore, ions traveling at the same speed but having different mass-to-charge ratios will be deflected by different amounts in the magnetic field.
