Magnetism and Matter

Q1.The relation B = μ₀(H + M) shows that:

• AB depends only on H
• BB is the sum of the applied field and the magnetization contributions
• CM and H are always equal
• DB = μ₀H for all materials

Q2.A diamagnetic material placed in a non-uniform magnetic field will:

• AMove toward the stronger field
• BMove toward the weaker field
• CNot move at all
• DOscillate between the poles

Q3.The magnetic inclination (dip) at the magnetic poles of Earth is:

• A0°
• B45°
• C90°
• DVaries seasonally

Q4.The Curie-Weiss law for ferromagnetism is:

• Aχ = C/T
• Bχ = C/(T - Tc)
• Cχ = C/(T + Tc)
• Dχ = CT

Q5.The angle of dip at a place is 30°. The ratio of the vertical component to horizontal component of Earth's field is:

• A1/√3
• B√3
• C1
• D2
