is yes it can be bent due to the curvature of spacetime produced by a strong magnetic field. I can give a very short answer why, without going into too much detail, how the resulting bent geodesics might look. Einstein's field equations state: Gμν = 8πTμν, G μ ν = 8 π T μ ν, Energy-Momentum curves spacetime.

Deflection in a magnetic field
When a charged particle cuts through a magnetic field it experiences a force referred to as the motor effect. Alpha particles are deflected by a magnetic field confirming that they must carry a charge. The direction of deflection which can be determined by Fleming's left hand rule demonstrates that they must be positively charged.

What happens when cathode rays affected by magnetic field?
It is well known that when the cathode rays traverse a magnetic field they are deflected from their otherwise rectilineal path, and in the form of tube ordinarily employed this deflection increases with an increase in the pressure of the residual gas in the tube. Table of Contents show.

Force on a Moving Charge in a Magnetic Field: Examples and Applications
The simplest case occurs when a charged particle moves perpendicular to a uniform B -field, such as shown in Figure 2. (If this takes place in a vacuum, the magnetic field is the dominant factor determining the motion.) Here, the magnetic force supplies the centripetal force Fc = mv2 / r. Noting that sin θ = 1, we see that F = qvB.

When solar wind particles run into a magnetic field, they are deflected and spiral around the magnetic field lines. Magnetic "field lines" are imaginary lines used to describe the direction charged or magnetic particles will move when responding to a magnetic field.
